Manipulation of Heat and Work Equations

  1. Feb 7, 2009 #1
    Dear all,

    How do you get from the 1st equation to the 2nd?

    dW = -RT dV/V

    dW = -RdT + RT dP/P

    Also, I’m trying to do the same for this additional pair below…

    dQ = C_V dT + RTdV/V

    dQ = C_P dT - RT dP/P

    Hi Wilson95, welcome to PF. It looks like you're assuming an ideal gas system; for the first set, note that


    I'm not immediately seeing how to handle the second set.
