    Re: volume

    PV=nRT approximately. I suppose T remains constant, n and R are constants. Thus if you go from 1 bar to 8.2 bar, then volume goes from 8 liters to 8/8.2 liters... Multiply by 1000 to get it in cm cubes.

    Didn't Petr Mugver practically gave you the answer already? Or did you not understand what you were given?
