First off, the reason N20 is so cold is because its EXPANDING. its an endothermic process (meaning it uses heat energy for expansion and conversion from liquid to a gas). Any gas kept at 800psi that is then expanded to atmospheric pressure would decrease its temperature drastically. Also by being converted from a liquid to a gas requires the evaporation process, which in itself requires massive amounts of heat energy to be absorbed into the substance.

Second, N20 is a stable chemical untill about ~560F where it breaks down and splits into Nitrogen and oxygen components. thus providing the oxygen needed.
