It's still losing its energy through infrared and visible wavelengths as well as other types of radiation no matter what. Just like the sun in space. This is why the inside of a thermos has a shiny coating, to reflect the radiation back to the contents.
Wow, now I know.
@I'm The sun can't necessarily a giant flaming ball.
@I'm why do you disagree
@I'm Flames need fire so it cant be in space. The sun is not on fire, its radiating, think of it more like a lightbulb. Its more of that than actual fire.(srry if your comment was a joke)
Edit: Sleep Deprived me put Fire needs flames. Fire needs oxygen to be alive so the sun isnt on fire, its glowing from the energy of nuclear fission(Idk if this is the right word).
@I'm Wrong, fire can be in space as long it has oxygen and fuel that's how rockets work, about the sun you forget that gravity exists and this creates an atmosphere, so no the surface of the sun it's not exposed to the vacuum of space
Radiating heat in a vaccum, isnt that what the sun does ?
Yup
It's called the greenhouse effect. Light hits the earth and the energy turns into heat
The earth does that too.
That is the reason why it gets cold at nigth.

Was hoping you would compare the time it took to cool to room temp as compared to a none-vacume.

As a result a potential loss of the ball might occurr.
I love how everyone seems to forget that the ball is resting on some nails. It's not floating in mid-ai... in mid-vacuum. So even if it didn't radiate heat, it would eventually reach equilibrium through conduction. I do believe the radiative heat transfer is faster in this specific case than the conductive heat transfer. Like _way_ faster. But it's not negligible long-term.
Reduced to the actual cause of the 'heat' - which is insanely intense motion of the particles (the constituent parts of the atoms) of the metal ball --
-- all you have to do to answer the question "how will the metal ball lose its heat?"
So another way to ask the same question is "what will gradually slow the motions (aka the kinetic energy) of the particles in the metal ball?"
1) the ball is 'transmitting' electromagnetic waves - and each electromagnetic wave the ball produces carries off energy from the moving particles in the ball. The electromagnetic waves that the ball is 'transmitting' are in the infrared and the visible light frequency ranges
2) the ball is held by a mounting 'seat' on a wood platform. As the ball's particles move around, they are in physical contact with the particles that make up the mounting seat. The motion of the ball's particles transfer motion to the particles of the mount.
ANSWER: to prevent the ball from losing 'heat' (aka intense motion of its particles) - you'd have to somehow stop its electromagnetic 'transmissions' and somehow cause it to 'float' and not touch anything.

Good catch. I missed that.
Glaring condition absent from the evaluation.
Yeah, that’s a pretty poor representation of a human hand vs red hot metal imo. Speaking as someone who has worked with 2000+F furnaces and has been burnt many times over the years. If it's hot enough, it will cut through flesh like a hot knife through butter. Especially skin, it's instantly gone. I have a nasty, thick scar on my upper arm from when I accidentally bumped into a ceramic plate that had just come out of the furnace. The furnaces typically have coolers on them that use liquid nitrogen like a cars radiator, except instead of coolant pumping through the system it's liquid nitrogen. But the cooler wasn't functioning correctly that day so everything coming out was extremely hot, actually 2000F is kinda on the lower end of the temperature we use in our furnaces, some of them get much hotter, although I don't know exactly how hot since I don't work on those myself. I only made contact with that ceramic plate for an instant and it cut right down to fatty tissue. Even if the coolers are working properly, anything coming out of the furnace is still hot enough to give you third degree burns for at least a few minutes. I have seen situations where furnaces were emptied with no cooling whatsoever, and being even within 15 feet of the exit of that furnace would have you dripping with sweat.
Yes. Should have used pork belly or such
Mmm the smell
Liquid nitrogen (or even water) for cooling furnaces -- wouldn't that cause cracking due to extreme thermal stress?
@@saeer5038 😆 yeah, like burning a steak
@@Lucius_Chiaraviglio it goes through several cooling zones with the last one being the most significant reduction. Yes, it can cause cracking if it’s not done correctly. The parts sit on a belt that moves very slowly, so it’s not a rapid process. The parts also typically sit on carbon, carbon fiber, or ceramic plates that kinda act like heat sinks and help to draw heat from the parts evenly. I mean, when we do the induction heat treat operation we use electricity to heat up coils red hot and basically instantly heat treat a part then immediately quench the part with coolant. I’ve never seen cracking being an issue with induction heat treat.
Actually incorrect mixture in the furnaces atmosphere causes the most significant defects (Assuming temperatures are correct). Parts will come out warped, cracked, or discolored. They usually come out your standard grey/silver color, but get too much oxygen in there and they’ll come out blue or even yellowish.
I don’t really work with the furnaces much anymore tbh, but I’ve just been doing it for so long I know quite a bit about it. My dad was a furnace technician, a veritable fountain of knowledge, unfortunately he passed a few years back.

The answer is in the title. "Red Hot". I.e. radiating energy in the form of EM waves in the visible spectrum.
Much more energy is being radiated as non visable infrared. Also convection and conduction are a much bigger factor in the ball loosing heat.

@@jaredf6205 Much bigger? Are you sure about that? I think people underestimate how big an effect radiative cooling can have.
Did these smart people at least skip to the end to see that it was explained in the video? Funny how they still felt necessary to explain it again.
@@jaredf6205
There is no convection in a vacuum. And on the observed time scale, as the presenter in the video correctly explained, the conduction was negligible. The ball cooled through radiative heat loss in this case.

Same thing when I saw the video title, but I still clicked it
Too arrogant
I think most people did,but didn't feel it necessary to tell everyone about it.
Cz sun can radiate in vacuum so will the nickel ball😂
Through infrared radiation
It's nice to remember that these vacuum machines can't even remotely reach full vacuum, the power is very small, there are many experiments that you can't do with them. An old mercury-based vacuum chamber would be needed, and yet it still has mercury vapors. So this experiment unfortunately failed in the question because there is still a lot of material to do the heat dissipation.
There are other methods to gererate a good vacuum then mercury based pumps. But the one in the video was clearly not sufficient to go below 20 mbar.
The reason the ball was able to cool down is the same reason the sun is able to heat up planets and other celestial bodies through the vacuum of space. This experiment successfully demonstrates radiation.
@@99mage99 The formula for heat loss by radiation is known, and it is much slower than heat loss by contact. Scientifically there really is nothing to say, it would eventually lose heat through radiation. But this was not demonstrated by the experiment, where heat was still lost through contact and not only through radiation. The concept pointed out by him is valid, the experiment is flawed.
Would be cool to see this one done again, this time with 2 spheres and with precise temperature measures on both: one in the vacuum, one in the open; would be interesting to see how different it goes, specially to see if the heat loss difference would be noticeable.
Yes definitely
It will be noticeable, the main difference is that on vacuum the loss happens by irradiation of light and other emissions!
In the air it would have also happen the transfer of heat.... Maybe is just a few seconds but for sure it will be faster!
Interesting anyway to see those tests!
Yes
@@anthonyaubert4074 It would also be faster out in the room because the walls is the vacuum chamber would keep it warm longer.
@@DANGJOS Liquid can only exist under atmospheric pressure. So in a vacuum, any ice melted into water would boil, dropping the temperature of the water until it re-froze the water back into ice. Also, any water vapor, which would hold the bulk of the heat, would be pulled out of the chamber. Water also has far more capacity to hold heat energy than air, or even metal. A complication would be that boiling water that freezes in a vacuum chamber has a tendency to shatter.
The heat will radiate through vaccum. Radiation can travel through vaccum.
Got to love thermodynamics
Yeah, expected to last longer though. Seeing radiation is the weakest form of heat transference.
@Sacred Icon explain hypothesis
@Sacred Icon but we can expect already proven results. The thing is don't believe something blindly, it's not science.
@Sacred Icon yeah strong belief based on evidence. Blind belief based on just belief and compel a person not to change belief. But expectation can go wrong and the person can understand it and change his KNOLEDGE accordingly ,that is science. Understand the difference.

Wow an actual original comment
I have never grasped the three methods of heat transfer more clearly than in this moment. Even though you barely used any words, the descriptions made the most sense of any explanation I have heard.

Hopefully you learned something as well.
Beats watching hentai
Try any object that vibrates (guitar string, a cymbal, etc etc) and put it in a vacuum chamber and see if it will stop vibrating.
It will
so vibrations dont go through our galaxy
It will stop
It'll stop because the tension on the string is acting upon it to bring it to a stop. But while it's in the vacuum chamber, it would be difficult to hear
It would stop
To verify results, you should also check how long a red hot nickle ball takes to cool down in normal atmosphere. An any difference would prove that heat is propelled via light.

This channel isn't to find truth or make scientifical experiments. This channel is made to seed in your brain lies. This author is a masonic puppy.
no, it already proves that heat is transferred via radiation. with your mechanism, any difference would prove that heat is transferred via air touching the ball.

This is a good example of heat insulation. As there are much less particles of gas in the vacuum chamber, less gas particles will be colliding with the hot particles in the nickel ball. Meaning there is not much to conduct heat from he ball
So, what you wanted was a reminder that, to no one's surprise, heat can move through a vacuum, thus proving that the sun is not actually a lie created by the Illuminati? The pointlessness of this video is staggering to me...
@@weissxritter Still people who didn't pass age 6 ?

You know that huge ball of hot glowing gas in space called Sun? You could have looked at that...
The segment with the silicone hand absolutely infuriated me.
"J-just, wait no- you can if you'd just- there, now ju- OH FFS!!!"
I remember when I was in high school, and had my fingerprints burned off... I was in welding, and someone didn't properly take care of a piece of 1/2" scrap that they welded. I guess they finished with it just before class was over, and during cleanup, I saw it on the table next to the scrap bin. Went to pick it up (stupid me without gloves) to toss it into the scrap bin, and it came up not even an inch off of the table, before sliding out of my fingertips. The way the ball reacted when placed on the silicone hand just reminded me of that.
Damn. Wow. Any estimate of how hot it was? That's crazy!
Have you ever been to jail? If so, how did the cops react to you missing your fingerprints?
@@ThePrufessa No idea how hot it was. It wasn't glowing anymore, but was still hot enough for it to just slide out of my fingertips. It wasn't a severe enough burn that my fingerprints didn't come back. They eventually did, but were smooth for a while after it happened.
@@ufninuyasha oh wow. That's amazing that they actually grew back! Thank you for replying!
@@ThePrufessa welding makes metal red hot. So assuming its AT LEAST 150+ °C
My dad has vissible scars from small bits of molten metal.
70+ °C can already cause burn scars on human skin.
I have a 1 by 1 inch but on my left wrist from 3 weeks ago when i had a small accident with 400°C hot metal. So burning your finger prints off. Probably between 150 and 250°C
If the metal wasn't glowing any ore it cud be still about 100°C i guess.
@@cherrydragon3120 great info.
Good video! A great thing to illustrate radiating heat would be a thermal imaging camera, or an IR temp gun, as they show you temps the object is radiating.
I feel it's worth pointing out that heat is most effectively dissipated in the form of infrared light, which would not be affected by a vacuum
Most effectively?
Idk about that chief, I get way more burned by touching red hot steel than I do from standing next to it.
Not most effectively. Radiation is the slowest form of heat transfer for a given temperature difference. However it is the longest ranged method, and the one that works well throughout 99.999999999999% of the universe
It would be very interesting to have another ball with the same initial temperature outside the vacuum chamber to notice the difference on the coiling time,
Also explains why you instantly feel the pyrotechnics at concerts, even if it is like 30+ meters away 👍
When the bombs blew up over Japan, powerful radiation from the blast propagated at the speed of light, meaning if you had a line of sight to the explosion, you were instantly affected, well before the shock wave or explosion materials hit.
Tom Haflinger got so dark so fast. From concerts to mass killings
@@THEDnARACER yeah, I could have picked something cheerier. How about, "That's why when you sit around a campfire, you're better off sitting upwind from it. The wind blows the smoke away from you, and the radiating heat isn't affected by air currents anyway."

What if the vacuum chamber had mirrors in it? Would that reflect the radiant heat back to the ball? Also a comparison with no chamber would have been nice.
*General Rule:* Don't use the word _absolute_ when talking about physical phenomena.
It is not possible to achieve a 100% vacuum. Even for "only" 99.9%, it requires special techniques and equipment.
Technically speaking, even the "vacuum" of (a non-trivial area of) deep space is not absolute.
How did he remove the air from inside the box? I would assume an open container does allow air to go inside of it.
@@wilFluffball it’s a closed container that seals up and has a vacuum hose attached to part of it to draw out the air from the sealed / topped container. Although I feel like while it is at a vacuumed state, there’s still the vacuum itself pulling the air (and potentially) heat out…
@@MysteryBatz Vacuums don't pull/suck.
@@CanadaBud23 then might I ask how does he get it to full vacuum to begin with? 🤔 at least for a short time, that air has to get pulled out somehow
Edit: that’s what I was meaning by the pulling, not the vacuum itself, but the obtaining of said vacuum
@@MysteryBatz You're not ever pulling a vacuum, that's a figure of speech. Pumps "push" the atmosphere out. The air trying to get in is the outside atmosphere pushing its way back in.

Cool experiment. Something to try if you do this again. Use magnetic levitation for the ball so it doesn't conduct through the nail. Also cover the box with a mirror to reflect back any heat.
Also, aim a some kind of temperature sensor at it. It would be obvious it’s losing heat but where would be interesting.
The ball can't be magnetised at high temperature, and some kind of electrically induced magnetism would be very difficult to set up. Perhaps possible, but technically very challenging.
The ball is like the villain who blocks multiple attacks from the heroes while loading up his power
I think you're underestimating the heat sink properties of the stand its sitting on. Would you be able to magnetically levitate the ball and redo the experiment? That would be AWESOME.

Get your grammar right.
That's our Sun... Eventually it will die
Wrong reason. The death of the Sun, at least in terms that most people would think of it, would be due to the lack of hydrogen plasma in the core to fuse, making it shrink, but this makes the hydrogen outside the core start to fuse, which rapidly and massively expands the Sun to about a diameter of 2 AU, or roughly the diameter of the Earth's orbit, give or take a few tens of millions of kilometres. Once the hydrogen in that has exhausted itself, the Sun will shrink to a subgiant, roughly twice the current diameter, but after some time of this building up the pressure, the helium in the core will be of such pressure and density that it can actually fuse, and so it will expand the Sun again. But helium fusion is very unstable and combined with having lost gas from the weaker gravity of the red giant phase, the Sun will be rapidly losing mass. By the time the helium is exhausted, the Sun will have lost it's outer layers, but the now carbon core can't fuse, as it needs too much pressure and heat to do so, so the Sun's energy source will evaporate, producing a white dwarf, roughly a third to half the Sun's mass in an volume approximately that of the Earth.
Considering that the full Sun has the mass necessary to pull on objects and keep them in orbit up to about a light year, or 12 trillion kilometres, away from the Sun, and has 99.8% of the mass of the Solar System with about 80% of what is left comprising of Jupiter and Saturn, squeezing even a third of that mass into the Earth's size with about 1/110th of the diameter, that should give you some perspective on just how dense that is.
This is the thing that will radiate it's energy out, especially in the form of X rays, over billions of years, and eventually, that stops as the Sun approaches a temperature equal to the rest of the solar system, and so will become a black dwarf, when the Sun will really, really be dead.
@@robertjarman3703 You only got it partially right.
@@carlosoliveira-rc2xt What did I miss?
I love this show. I always learn something new.
"No medium to transfer heat" as he continuously pumps out non air.
The pump keeps running after the chamber reaches full vacuum to keep it from pressurizing
@@SJNaka101 But that still tampers with it. It's not a 'SEALED' Vacuum like Space would be on all sides for millions of miles in all directions. So the Suction could still mess with whatever test is going on, especially with anything that deals with atoms moving. Such as heat.
@@SJNaka101 Thats why there is a check valve. At the moment I cant believe he isn’t pulling out heat in some way. Nor has he defined he has a check valve.
So cool
*WHO ELSE IS EXCITED FOR CHRISTMAS?* 🎅🎄🎁
Definitely, Radiation is super cool!
Not me. 😑🧠💤
No, but lex from bookworm adventures deluxe will.
and WITHOUT a vacuum
How do you end up in every video i watch. Its really a ripoff of bookworm adventures deluxe.
I don’t get it
Beef Stew wait wut
So is without a vacuum meaning in regular air or some hypothetical hyper vacuum.
damn i remember playing that game when i was a kid
I love the way you enunciate words 🙃
0:33 What I said to my girl last night.
What happens if you put molten metal in the vacuum camber?🤔
It will give away its heat by radiation and solidify
It's actually MOLTEN metal, not "melted"
It would de-gas then solidify, possibly at the same time if the metal has the proper melting point. Would be cool to see how different alloys react
I think you are hoping it will become foggy like water does in space. But you have to understand here it will not be free from gravitational pull so it will just rest at the bottom of the chamber
Depends on the metal. Molten mercury and molten tungsten will have vastly different results.
According to the UA-cam dictionary,
That is a 1000 degree red hot steel ball
This vacuum chamber is probably the best investment this guy has ever made.

For a second I thought he said "the heat death of the universe is extremely far away, about 10 to 100 years away." Haha
Because photons travels without any medium.
nope. They have medium. Space.
@@RKroese Nope, EM waves don't a need a medium. There is ISM in space but it has nothing to do with propagation of EM waves.
@@RKroese and time
@@kingsman428 yes it does, because space has a structure to it
@@colto2312 time is movement in space and is a construct of the spirit, like love or truth.
Hey man I love your video's
I got 1 question that I have beet thinking about for the last few days:
Why does a room with a temperature of lets say 20°C feel warm to your body (37°C) it doesn't make any sense to me, it would be much more logical if everything under 37° felt cold to your body, and everything above warm?
(Maybe a stupid question😂)
Actually is a good question. I think it might be that we actually sense the rate of heat transfer as opposed to actual temperature. So if you touch metal it's colder than wood at the same temperature, but the metal conducts better and so transfers the heat from your body faster. Maybe....
37C will feel hot, because you produce heat and you have to get rid of it so you don't overheat. As you produce a lot of heat, the temperature to not overheat is roughly around 20C with clothes on. While there are a lot of factors involved, it basically explains the principle.
Clothes do a lot here, so 20C naked will not feel warm over time, unless you are used to much colder temperatures (because your body can adjust heat production to a certain extent. That's why you see more people in spring wearing t-shirt than at the same temperature in fall)
There is also some kind of adjustment that you don't really notice, when you sweat so little that it can evaporate quickly, so it doesn't build up.
Does that answer your question?
Edit: oh, and you will produce heat as long as you live, because biochemical reactions that make your body work are exothermic. The reaction (plus the friction between the cells) that "feeds" your muscles (turning sugar into co2 and water) for example is a strongly exothermic reaction. That's why the same temperature feels even warmer during exercise. (And your body utilises that when you are cold by shivering)
Stupid question? no. But very amature. Im hoping you are 10yrs old
@@shahrukhs1637 actually it's a good question. The only irritation is your 'know it all' attitude. I hope you're only 9 years old.
It depends on rate of heat loss from your body,if the loss is high, it feels cold, if the heat loss is low it feels warm, if you are gaining heat, it feels hot.
That's why 30 degree water feels cold but 30 degree air feels comfortable.
I'm not surprised haha. If we had a way to keep metal hot forever we would be using it for energy
It's freakin' hot this summer. "Heat-death of the universe" sounds pretty comfy right about now.
Redo this. Cover the inner wall with shiny aluminum foil and put the camera inside or add a small hole for the camera to see inside
Then there would be oxygen or the camera would melt
He obviously meant a hole in the foil....
No, due to radiation.
Same reason stars can get cold
It's just slower
#didntneedthevideo
Ok, you’re cool
Put this in liquid nitrogen
The fact that it’s glowing by itself makes it obvious it can’t stay hot forever. The energy for the flow has to come from somewhere.
1:10 thats not eaven close that ball would almost go trough the hand and compleatly destroy it in real life
is it just me, or does "red hot nickel ball" sound baller?
I think it sounds stupid if you're not really heating nickel. Why blanket every hot metal under one metal?
@@ThePrufessa Look at this Photograph.
@@knownas2017 what are you talking about?
"Red Hot Nickel Ball" is the name of my Red Hot Chili Peppers/Nickelback crossover tribute band.
@@Dargonhuman when and where is your next show?
We already know that in space you would cool down to almost absolute 0 aswell
Nah, probably 2.7 Kelvin, or however the physics would work out. The microwave radiation all around would probably keep you from dropping too low in temperature
it'd take a pretty long time, and if you got out of the planets shadow regularly you'd probably stay warm even longer
@@nikodemossowski4621 Even if you placed in the middle of a void, it still would never reach absolute zero. There's still energy coming in from distant galaxies and the microwave background radiation.
The energy crisis solved!! Good work!!!
This might be hot
But still
Man's not hot.
First mwahaha 😋😋😂😂💖💖
Because I clicked on it accidentally but I’m not mad 😊😊💖💖
You sound evil

@@spreadlove8624 Its like saying "I might be stupid but it depends on how you define stupid"( in this case in which you already are).Do you think that a person who knows proper English might define evil as something morally good and right?
Isaam Thalhath Well in the modern day you can be a funny evil, sexy evil, cartoon evil or old fashion pure evil. Stupid can be funny stupid, cute stupid or low intellect stupid. You seem to think really two dimensional with little imagination 😂😂
You almost scared my poor grandma to death. She thought you said that the heat death of the universe is around 10 to 100 years away. XD
I was thinking about this stuff couple weeks above. Thanks for doing it
