Relation between h and u

WebIn a system, the sum of energies is called U. H=U when work is done=0. What is the distinction between enthalpy and energy? Enthalpy is measured in both joules and joules per mole, but energy is only measured in joules. Enthalpy is a form of energy as well. Enthalpy is always the energy change between two states, but energy is a state of the ... WebJan 14, 2024 · Re: Difference between delta H and delta U. Delta H is the change in enthalpy and Delta U is the change in internal energy. Internal energy is the amount of energy a system has. However, we must realize that a system doesn't exist in a vacuum. Rather, there must be some sort of change in volume/pressure because of the presence of a system.
