Thermodynamic Properties

Internal Energy (U): The total energy contained within the system, including kinetic and potential energies of molecules.Enthalpy (H): H=U+PVH = U + PVH=U+PV

• PPP: Pressure
• VVV: Volume

Entropy (S): Measures the amount of energy in a system that is not available to do work.Gibbs Free Energy (G): G=H−TSG = H – TSG=H−TS

• TTT: Temperature
• Used to predict the spontaneity of a process.
