Homework Help: Working gas problem.

  1. Dec 4, 2014 #1
    1. The problem statement, all variables and given/known data

    2. Relevant equations

    pv = nRt
    3. The attempt at a solution
    The answer is zero because it does not move since no work is being done.

    Doesn't the volume change?

    This is pretty disturbing. Firstly, the problem says "this process is8000 J.". Secondly, no, the answer is not zero. I am quite confident about that.

    Okay since we know it not zero then if 8000 work is being done than is the problem reiterating the work that was done so A?

    Show us your work.

    From where did you get this problem (please tell me)? I don't want to buy the book by accident.

    No, it's not A. How is work defined when gas expands? In this case the process is isobaric meaning pressure is constant.
