Question on work

  1. Apr 22, 2014 #1
    1. The problem statement, all variables and given/known data

    "An insulated box is initially divided by a frictionless, thermally conducting piston. One side of the piston is 1.5(m^3) of air at 400k, 4bar. The other side is 1.5(m^3) of air at 400K,2 bar
    The piston is released and equilibrium is attained, with the piston experiencing no change of state"


    the solution assumes W=0. why is this?

    2. Relevant equations



    3. The attempt at a solution

    That's the work for the entire system, not the work between the two chambers. Since the entire system is in a isolated box, there is no external work or heat.
