An expression for the latent heat of vaporization of a fluid is formulated employing renormalization-group theory predictions for the thermodynamics of fluids in the vicinity of the critical point. A least-squares fit of the latent heat data of water is made using the general and relatively simple...
We provide detailed background, theoretical and practical, on the specific heat of minerals and mixtures thereof, ‘astro-materials,’ as well as
