Volume of gases

  1. Apr 12, 2012 #1
    1. The problem statement, all variables and given/known data
    I was studying about gases..and a thought struck me: we are taught that gases have no fixed volume. They occupy whole of volume of container in which they're placed.
    so what are we trying to calculate by the equation PV=nRT . I mean at a particular P T and n,
    place the gas in containers having different volumes.



    2. Relevant equations



    3. The attempt at a solution

    hi babita! :smile:
    you can't … if V is different, then one of the others must be different also (usually the pressure)

    that's why the equation is important! :biggrin:
