Homework Help: PV in a Cylinder

  1. Mar 25, 2010 #1
    1. The problem statement, all variables and given/known data

    A vertical cylinder with 500 moles of a monatomic ideal gas is closed with a 50kg piston with an cross-sectional area of 100cm. V_initial = 1 m^3. T = 300K, The Piston is then released and stops at the equilibrium position. Ignore friction.

    1) Find the equation for the Work done by the gas in terms of Volume

    2) Find the final volume of gas

    3) fin dthe final temperature

    2. Relevant equations



    3. The attempt at a solution

    Part 1)

    Work done by the gas...

    dW = Pdv from v=1 to v = nRT/P

    W = P(nRT/P - 1) = nRT - P <-- Is this correct... I now put it interms of V

    W = PV - nRT/V
