Homework Help: Question About Thermodynamics

  1. May 5, 2009 #1
    1. The problem statement, all variables and given/known data

    An ideal gas is enclosed in a cylinder that has a movable piston on top. The piston has a mass m and an area A and is free to slide up and down, keeping the pressure of the gas constant. How much work is done on the gas as the temperature of n mol of the gas is raised from T1 to T2? (Use T_1 for T1, T_2 for T2, and m, A, R, and n as necessary.)

    2. Relevant equations
    W=- integral of P dV from Vf to Vi ( sorry I was not sure how to format this!)
    3. The attempt at a solution
    I was not sure how to go about doing this. Do I set the ideal gas law equal to volume and then plug that into work?

    Is this work done on the gas or by the gas?

    It's the work that is done on the gas I believe.
