Why is it that when I do whippets the nitrous is freezing cold when it comes out? How does it stay the cold when I can't feel the cold when it's sealed?

just molecule losing momentum when hitting an expanding container.

So does that mean it's really hot when it's sealed inside?

Just after filling, yes. Of course it cools down right after that.

Take it with oxygen (30:70 ratio) and iv benzodiazepine for moderate sedation.

The ideal gas law doesn’t seem like enough. We know that dP<0, dV=0, and dn<0. dP*V+P*dV is negative so R*(dn*T+n*dT) is negative.
We have negative + positive * unknown = negative. This is insufficient right? What else do we need? Entropy?

Real gasses dont follow the ideal gas law.

Entropy is irrelevant. Adiabatic expansion/cooling occurs. Because the nitrogen expands way too fast for any significant heat transfer to occur, we have dU = -PdV which is a negative number. U is function that increases monotonically with temperature and so dT is negative. The gas cools because it adiabatically expands.

If you want it to be warm, just heat it up on one of your stove elements before hand

Why do molecules lose momentum when leaving a small container, into free space?

Because they do work to the surrounding air and that uses up the energy.

You would know if you took chemistry in high school like everyone on this board already should have. The reason is that the average speed of the particles goes down when you give them more room, translated into science, the temperature goes down when the volume increases and the pressure decreases. Objects in contact will reach thermal equilibrium. The pressurized gas is perfectly room temperature before it is depressurized.

28 is not zoomer, I'd say the cutoff is more like 21
