>>14197049some physicist/engineer/chemist noticed that you can rewrite free energy in thermodynamics using an expression similar to entropy. they wanted to get famous and invent a third sort of pseudo-energy (whereby entropy is the second version of energy). it kind of caught on, but not really. enthalpy, as well as entropy, are just different representations of energy.
Entropy is a quantification of energy associated with statistical fluctuations (i.e. thermal energy associated with probability distributions).
Enthalpy is energy associated with geometric configurations of engines. In other words, it's just a different version of thermal energy, that's all.
