Internal energy, E, which is the sum of the kinetic and potential energies of the particles that form the system. The internal energy of a system can be understood by examining the simplest possible system: an ideal gas. Because the particles in an ideal gas do not interact, this system has no potential energy. The internal energy of an ideal gas is therefore the sum of the kinetic energies of the particles in the gas.
Enthalpy (H), which is the sum of the internal energy of the system plus the product of the pressure of the gas in the system times the volume of the system.
H = U + PV
