Physics- work and heat

  1. Nov 27, 2007 #1
    1. The problem statement, all variables and given/known data



    A heat engine using a monoatomic gas follows the cycle shown in Figure. Part 2®3 is adiabat, Vi=101 cm3, Vf=668 cm3, Pi=118 kPa, T1=315 K.
    Find Q for process 1 to 2.
    Find Ws for process 2 to 3.


    2. Relevant equations
    PV=nRT
    Q=nCv(delta T)


    3. The attempt at a solution

    I found moles to be 0.0045. But, I don't know where to go from there. I don't know how to find the tempertaure for step 2 and 3.
    please help

    the picture is added as an attachment.
