Why Enthalpy Values are Gaining Attention in the US

Enthalpy is a thermodynamic property that represents the total energy of a system, including internal energy and the energy associated with the pressure and volume of a system. It's a measure of the energy required to change the state of a substance from one phase to another, such as from solid to liquid or from liquid to gas. Think of it as the "total energy budget" of a system.
