Decoding the Enthalpy of Formation: A Guide to Chemical Thermodynamics - dev
Enthalpy (H) and internal energy (U) are related but distinct concepts in chemical thermodynamics. Internal energy represents the total energy of a system, including both kinetic and potential energy, while enthalpy is a measure of the energy associated with the pressure and volume of a system. Enthalpy is typically used to describe the energy changes that occur during chemical reactions, while internal energy is used to describe the energy changes within a system.
