Define internal energy class 12
WebInternal energy definition, a function of thermodynamic variables, as temperature, that represents the internal state of a system that is due to the energies of the molecular … WebInternal energy (U) is defined as the total energy of a closed system in chemistry and physics. The sum of the system’s potential energy and kinetic energy is known as internal energy. When a reaction is run at constant pressure, the change in internal energy (U) is equal to the amount of heat gained or lost (enthalpy change).
