is there any PV work done during phase changes? I understand for ex- water from -10c to 0c, as heat is supplied, the molecules move faster and the energy is used to raise the temp.
Q =mct
but when water reaches 0c, the temp stops rising and doesn't the volume increase? So there should be some W done by the substance, correct? If so, then why do we call that as the heat of fusion, change in enthalpy = q
