Thermodynamics - Piston Cylinder

  1. Sep 30, 2007 #1
    1. The problem statement, all variables and given/known data

    2. Relevant equations
    Work = Pressure * Change in Volume

    3. The attempt at a solution
    Note : V without a line signifies specific volume, V with a line across it specifies volume.

    First, can you check if my attempt for #1 is correct?

    I am confused on what to do for #2. First of all, how do I apply the equation given above if my pressure is changing? (From 1.0 Mpa to 0.5Mpa), do I just subtract them? Second of all, how would I find the temperature?
