Three diffrence between U and H

1.	Three diffrence between U and H
Answer» In thermodynamics, the internal energy of a system is the energy contained within the system, excluding the kinetic energy and potential energy.Change in internal energy is denoted by ΔU.Enthalpy is the amount of heat content used or released in a system at constant pressure.Change in enthalpy is denoted by ΔH.1)The heat given off or absorbed when a reaction is run at constant volume is equal to the change in the internal energy of the system.2. The heat given off or absorbed when a reaction is run at constant pressure is equal to the change in the enthalpy of the system.
