Homework Help: Understanding PV Diagrams - Work

  1. May 8, 2008 #1
    1. The problem statement, all variables and given/known data

    Calculate the work done by the gas during process 1-> 3-> 6.
    Express your answer in terms of Po and Vo.


    2. Relevant equations

    W=integral(pv) from V1-V2
    W=PVln(V2/V1)

    3. The attempt at a solution

    3Po*V*ln(3Vo/Vo)

    I'm not sure what I'm doing wrong, it keeps telling me I'm off by a multiplicative factor.. Should I be using W=nRT ln(V2/V1) ?
