Review of Thermodynamics

Equilibrium thermodynamics is the branch of physics which studies the equilibrium properties of bulk matter using macroscopic variables. The strength of the discipline is its ability to derive general relationships based upon a few fundamental postulates and a relatively small amount of empirical …

(In North America the term «furnace» is normally used if the purpose is not actually to boil the fluid.)
