Homework Help: Graph Question

  1. Dec 10, 2009 #1
    1. The problem statement, all variables and given/known data
    A monatomic gas at 27degrees C undergoes a constant volume process from A to B and a constant pressure process from B to C, as shown in the figure below:

    Find the total work done during these two processes.


    2. Relevant equations
    Not sure...

    3. The attempt at a solution
    I know I have to find the area under the curve, but I'm not sure how I have to relate the ATM's (pressure) to volume.

    Yes, the work done is the area under the curve. For process AB, is any work done? For process BC, the area formed is a rectangle.
