Consider a phase transition at constant pressure p
(eg. solid-solid) which is accompanied by a (slight)
change in density.
I want to calculate the heat which is available for
changing the temperature at the position of the phase transition.
Is it just the latent heat Q which follows from
the Clapeyron-equation: dp/dT = Q/[T *(delta V)]?
Or is it the inner energy (delta U) from the first
law of thermodynamics: (delta U) = Q - [p *(delta V)] ?
Hints appreciated ...
