WebDec 8, 2024 · In chemistry and physics, internal energy (U) is defined as the total energy of a closed system. Internal energy is the sum of potential energy of the system and the system's kinetic energy. The change in internal energy (ΔU) of a reaction is equal to the heat gained or lost ( enthalpy change) in a reaction when the reaction is run at constant ... WebEnthalpy is a thermodynamics property of a substance and is defined as the sum of its internal energy and the product of its pressure and volume. H = U + PV. Specific Heat (c) Experiment shows that the temperature rise of liquid water due to heat transfer to the water is given by. Q = m c (T 2 - T 1) where.
