Thermodynamics soap bubble

  1. Apr 19, 2016 #1
    For a system modelling a soap bubble, the differential work done is now given by:

    dW = −pdV + γdA, where γ is the surface tension and A the area. Compute new differential expressions for the potentials U, H, F, G. What are the new natural variables in each case? Are there any new Maxwell relations?

    Hi Zero. This looks like a homework problem, can you provide more context as to where the problem is sourced from, and what you've already done to try and solve it?

    not homework, Its revision of past exam paper.
