Any gas could be seen as a liquid and vice versa, depending on their pressure/temp combo.

Nitrous oxide in liquid form will turn into gas if let out of the bottle and expands/heats a bit. At that stage it will absorb a lot of heat as it changes state from liquid to gas.
That is what I need to know, how many kCalories will it absorb per mass unit.
I searched all over the internet, but nothing. I suspect that it's about 1/3 of that of water (similar to ethanol), but I'm not 100% certain.

I know it's a silly comparison, because nitrous will also cool the intake charge in ways water cannot. But we're talking in-cylinder cooling here, and latent heat of evaporation is the game. :wink:

This guy sells both W.I. and Nitrous systems, and believes that even a tiny shot of NOS renders WI totally redundant.
I just want to see if he is correct.
