Have you ever noticed that when you empty an aerosol can, the temp of the outside of the can drops dramatically as the contents in the can decrease? Sometimes it'll even get frost on it.
Same thing happens with a propane tank as it empties. I'm not a physist but maybe someone else on here is and can explain it better.
Hell, I can't even spel Physisist!!!!
