    1. The problem statement, all variables and given/known data
    What is the temperature at 0 atm? Also what is its significance?

    0 atm implies no gas present, so classically it couldn't have a temperature.
    It would have the temperature of the surrounding pressure vessel but that might not be a useful definition.

    Interesting. However... at 0 pressure, there may be 0 temperature, which could theoretically exist,though it would cause all materials around to freeze due to diffusion. This might cause the Universe to freeze, though.
    oh, btw, im an amerature at this :frown: i don't really know what im talking about.
