Consequences of an Ideal Gas Internal Energy a Function of T Only

A New State Function for Any System: Enthalpy H = U + PV

A New State Function for an Ideal Gas System: Entropy

Another State Function: Helmholtz Free Energy: F = U - TS

Another and Friendly State Function: Gibbs Free Energy: G = U - TS + PV
