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 10 месяцев назад

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 6 месяцев назад

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 6 месяцев назад

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

Always wanted to know this! Fantastic explanation as well!

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

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

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 7 месяцев назад

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

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

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.

Why? International shipping of pharmaceutical reagents.
