in general, by lowering it's energy

>>8699584
tried that, didn't work

>>8699605
Increase pressure a lot.

>>8699583
I usually just wait for a big freeze to happen to the entire universe, you could also create your own universe and program your helium to solidify faster.

Heike, you dummy

>>pressure isn't important

Ask Willem how he did it

Brainlet here.

Wouldn't an increased pressure entail higher temperature and thus more energy?

If the answer to the previous question is 'yes', is it just that there's some limit at which this principle no longer applies?

how do I get an owl? I want an owl

>>8699800
gas doesn't necessarily have higher energy than a solid, lower pressure means less energy is required to maintain a gaseous state, if you increase the pressure enough it eventually becomes solid in spite of the energy, different chemicals have different thresholds for their physical state

>>8699800
when you compress gasses, their temperatures go up. you generally need to cool things that you're compressing too.

Liquid helium/hydrogen tanks typically need continuous cooling at STP because if you don't the tanks leak too much gas

>>8699800
Um, think to yourself. Is a pressurized canister hotter? Pressure only refers to how close the particles are together.

>>8699583
Cool it to 2 kelvin at a pressure of 5 MPa

>I want an owl
Me toooooooooo

>step 1: Go to an owl sanctuary

What does solid helium look like anyways?
