Web7 dec. 2011 · What is the difference between Energy and Enthalpy? • Energy is only measured in joules, but enthalpy is measured in both joules and joules per mole. • Enthalpy is also a form of energy. Energy is a state of the matter, but enthalpy is always the … Web22 jun. 2024 · Enthalpy is defined as. H = U + p ⋅ V, where. U is system internal energy, p is system pressure, V is the system volume. If we consider constant pressure ( isobaric ) scenario, the above equation in the difference form is. Δ H = Δ U + p ⋅ Δ V = Δ U + W, where W is the volume work done by the system on the surrounding.
