Work done during state change

  1. May 9, 2009 #1
    I'm not rlly sure whther work is being done during melting or frdeezing. How abt during boiling, evaporation and condensation. I knw that for work to be done, a force has to be done over a certain distance. However, I'm not sure if the force required to overcome atmospheric pressure is considered as work being done. Pls help. Thanks.

    Well, you obviously know that there is a force... now is there a (nonzero) distance? In other words, does the force make something move? If so, then work is being done.
