Re: Specific Heat

No law prevents the heat capacity from varying within a single phase. In
fact one of the first illustrations of the macroscopic effects of
quantum mechanics is the calculation of the temperature dependences of
the specific heat of a solid using either the Einstein or Debye models.

The specific heat of water does vary with temperature (but not much).
One source I googled on the web gives data that the specific heat of
water varies by about 1% from 22 degrees C to 100 degrees C.
