Question
In thermodynamics, the internal energy of a system is the energy contained within the system, excluding the kinetic energy of motion of the system as a whole and the potential energy of the system as a whole due to external force fields.
Enthalpy is a measurement of energy in a thermodynamic system. It is equal to the internal energy of the system plus the product of pressure and volume.More technically, it includes the internal energy, which is the energy required to create a system, and the amount of energy required to make room for it by displacing its environment and establishing its volume and pressure.
Difference is
Internal energy (U) is basically How much energy a system has. But Enthalpy (H) is the thermodynamic potential of a system and is the sum of internal energy and the product of pressure and volume of a system.
Internal energy does not include the energy due to motion or location of a system as a whole but enthalpy includes the kinetic and potential energy
