What Happens If You Put Dry Ice in Liquid Nitrogen? 🥶🧊

Welcome back to the Tommy Technetium channel. A new chemical experiment awaits you in this science video. Let's see what happens when you mix dry ice and liquid nitrogen. What will be the chemical reaction? Stay tuned for more amazing chemical lessons!

I think the initial plume of "smoke" is more likely nitrogen, because you've put a solid at above the boiling point of ln2 in ln2, past the vapor barrier, which facilitates rapid transfer of energy

[@TommyTechnetium]

In order to see the nitrogen, it needs to condense, but there's nothing in this experiment that's cold enough to condense nitrogen

[@jackfang58]

I think that's always confused me in chemistry is the actual point of time it transfer between phases. I know there is phase diagram that can probably show this but why does the dry ice initially sublimes then freezes? Shouldn't it instantly stop subliming?

[@TommyTechnetium]

Substances must lose energy in order to freeze. It takes time for energy transfer to occur. Because of this, the surface of the dry ice remains above sublimation temperature for a time before transferring enough energy to the liquid nitrogen to remain solid CO2

Great job Dr. K! This always amazes me to see! 😊

[@TommyTechnetium]

Thank you 😊

[@MadScientist267]

Dude your channel is *severely* underrated

[@TommyTechnetium]

Thank you 😊

Magnesium flash powder in liquid oxygen

[@TommyTechnetium]

😳

[@ChemEDan]

@@TommyTechnetium I really do wanna see it though... proper safety precautions of course.

[@ZBREAD.]

Always wanted to know this! Fantastic explanation as well!

[@TommyTechnetium]

Thank you 😊

[@benjurqunov]

I worked at a gas plant.
Aside from helium, We made most everything there, pulled it out of the atmosphere.

[@photonik-luminescence]

Nice video !

[@TommyTechnetium]

Thank you 😊

I seen in one video a magnesium reacting with nitrogen one the oxygen from the glass is depleted. I really thought it wouldn't react with nitrogen. However it reacted the same as it would with oxygen.
What i would like to see a magnesium reacting with liquid nitrogen, but with extreme safety precautions.

[@TommyTechnetium]

I've never tried this but have always wanted to. Thanks for reminding me

[@SouthernTechie]

I would love to see the reaction of s terrarium with ants and some sort of small plants would react to being exposed to liquid oxygen for over a month. I would say do something like Chia seeds since they grow super fast I'm curious if it would change the way the plants grow and how big the bugs get.

I watched the candy food color video on how sugar water can stop each color mixing because of density in sugar water, i couldn't comment on that because its for kids so that is turned off. Anyways im wondering if it would do the same thing with sugar free candy if you can find sugar free m&ms but wonder if it will be different. Also when watching that it reminded me so much like footage i saw of the ocean and freshwater met and its a huge drastic different appearance and you can see a sharp boader line, and i bet its because salt water is doing the exact same thing as the sugar water had done.

[@TommyTechnetium]

Fantastic observation and idea for future experiments. Thank you!

[@JohnPlantefaber]

Curious as to how this might translate the culinary world even further as they do now.

[@joshentheosparks7492]

Answer I came for: does dry ice contract when put in liquid nitrogen?
The answer I got: no, but it sublimates what isnt at -192c, making more room for colder dry ice.

[@joshentheosparks7492]

Why? International shipping of pharmaceutical reagents.

[@chartreusemaiden604]

I love you videos

[@TommyTechnetium]

Thank you 😊

[@PULLTHEPARODYLEV4R]

Even something as cold as this stands no chance against how cold my dad makes the ac in our house 🥶

[@TommyTechnetium]

😂

[@PiedmontPerkYT]

Cool! (No pun intended haha)

[@TommyTechnetium]

😂

[@nate8688]

Looks like a waterfall

[@chinmayeelenka9589]

Cool 😎🤠

[@TommyTechnetium]

Thank you 😊

[@Chownio]

What happens if you scream at dry ice?

[@TommyTechnetium]

I don't know....what?

[@michaelbailey4164]

That's dry humor
