      very much so. A question: would a glass container immediately break when filled with liq He? If not, doing so in very dry air might have shown the color of liq.He. Or would O2 and N2 sublimate too fast on the outer surface?

      In some of the earliest videos (from around 2008 IIRC) he is completely un-censored. He doesn't say much, but he is very obviously talking. Niel speaking kind of like Waylon Smithers from the Simpsons: everyone knows him as being yellow, but he was once a black character if you look far back enough.
      Regardless, it's still great to see him "break character".

      @-yeme- 7 років тому +1

      I expect its just because a He atom is so small it slithers through stuff relatively easily. its not like it would flow through glass unimpeded, like you could still put helium in a bottle, but it must happen fast enough to spoil the vacuum of a thermos if you use one for He

    • @Bodyknock
      @Bodyknock 7 років тому +6

      Liquid helium is a superfluid, it has zero viscosity, so it can flow through pores as small as a nanometer. That also allows it to do other freaky things like stay still if the container is spinning or to climb up and over the walls of its container on its own.

    • @-yeme-
      @-yeme- 7 років тому +2

      I dont think the ability to diffuse through glass can depend entirely on its superfluid properties, I looked at a few abstracts and lots of work has been done on gaseous helium diffusing through glass at much higher temperatures, -100°C to +500°C. maybe theyll talk more about it in the next video

  • @BeCurieUs
    @BeCurieUs 7 років тому +15

    Helium is awesomely stable in the nuclear world as well. It is SO stable compared to its neighbors, it is one of the few elements you can fission to bellow iron and still make a net positive energy! IE you could split a lithium to get you some helium a net positive of energy. This is basically unlike any light element! You can google "nuclear binding energy curve" to understand this. Anything that increase your binding energy will net you an energy release. Most of the other peaks you see you can't really reach via fission, helium via lithium and sometimes beryllium are the only ones that work (cause fission will net you roughly 2 equal sized parts (one usually a little bit larger) and that just doesn't add up with most of the light stuff)

    I anticipate that the only valid reason someone would have cause to dislike this video is how much helium is "wasted" in the video. Many are worried about the Helium shortage. However, there are orders of magnitude more egregious examples of helium waste happening every day. So if someone disliked this video for that reason, it would be quite short sighted.

    Just a thought. Thanks for doing this!!!

      Unfortunately, silicon would lose its semiconducting properties at temperatures that low, so the chip simply would not work.

    • @lajoswinkler
      @lajoswinkler 7 років тому +9

      Even if it would not cause the chip not working (Aggropop explained why), it would be useless. Its thermal capacity and conductivity are very poor. Extremely cold absolute ethanol (or glycol mixtures) under high circulation are much better. They have enormous capacity and conductivity and wet the surfaces without boiling off and creating even worse bubble zones.

    • @TheOrbitalDropShock
      @TheOrbitalDropShock 7 років тому +1

      You are saying that it has too poor thermal capacity and conductivity to be effective, yet you think that the silicon losing its semiconductivity due to the low temperature is a possibility? Interesting..

    • @Aggrop0p
      @Aggrop0p 7 років тому +3

      It's not as effective as liquid nitrogen, meaning it will cool something (reduce the temperature/absorb heat) more slowly and you will need more of it to sustain any particular chill point. It will ultimately reach a much lower temperature than liquid nitrogen can though.

    Could you the thermis in a vacuum chamber? Removing the air might reduce the fog? Or will it boil more?

    If helium emits a yellow liɡht, can someone explain to me why a purple liɡht is emitted when helium and deuterium are fused?

    • @lancebradshaw4829
      @lancebradshaw4829 7 років тому +3

      It's a different process. The light emitted by a neon light comes from excited electrons dropping back down to lower energy levels. That produces a very characteristic wavelength. I presume the light emitted from a nuclear fusion reaction comes from the very high temperature of the gases involved (incandescence). The color of the light is spread over a swath of different wavelengths (i.e. black-body radiation) and is directly related to the temperature of the gas.

    Lol Neil's reaction in the beginning... Priceless... Helium in liquid form is really cool (no pun intended) to see. All this time people were led to believe liquid Nitrogen was the coldest and here helium actually is. Mind.... Blown.... Really love your videos, all. I've watched nearly all of them so far and some more than a couple times.

    So if helium forms near radioactive materials then by burying our spent radioactive materials in the ground are we inadvertently making giant helium deposits for future millennia?

      Not exactly 'giant'; helium is forming all through Earth's crust and interior, seeping upwards through the rocks and collecting in gas pockets. Compared to the rest of Earth our waste is puny. Dangerous but puny.

    From where does the helium picks up the two electrons?

    • @heinrichberger3908
      @heinrichberger3908 4 роки тому

      Probably from the atom that decayed. When this looses two protons, two electrons will be redundant.

  • @jamesm3985

    Is it possible that the music from the phone only got quieter because helium is on one side of the speaker and possibly air on the other side? So, maybe it is making it harder for the cone on the speaker to vibrate correctly like a diaphragm with two different pressures on each side making the diaphragm more rigid. I ask this because I learned sound travels faster through helium and this goes against that. Is it possible to do the same experiment but use an open speaker instead?

    I wished the professor would answer this. Why does helium work better for TIG welding and produce more heat input than Argon? And does any of the other inert gasses somehow work better than either of those?
