Delta H: The Ultimate Guide to Understanding Enthalpy and Energy Changes - legacy
At its core, enthalpy is a measure of the total energy of a system, including both internal energy and the energy associated with the pressure and volume of a system. It is often used to describe the energy changes that occur during chemical reactions, phase transitions, and other thermodynamic processes. Enthalpy is typically measured in units of joules (J) and is represented by the symbol ΔH.
