impossible definition of latent heat (part 2) #148

Open JohnDenker opened 8 years ago

JohnDenker commented 8 years ago

In the box on page 541, associated with section 20.3 and/or 20.4, it equates the specific transformation energy with the traditional latent heat.

However, the actual tradition defines latent heat in terms of enthalpy, not energy. The distinction is sometimes quite significant.

This affects the same sentence as #147, but it raises a different conceptual issue. Technically one "could" define a non-traditional latent energy, although I don't recommend it. In contrast, a definition of L in terms of Q is dead on arrival.
