Unraveling the Mystery of Enthalpy Change: A Closer Look at the Formula

For those new to the concept, enthalpy change refers to the measurement of the energy change that occurs during a chemical reaction or physical process. It's a measure of the total energy of a system, including internal energy (U) and the energy associated with the pressure and volume of a system (pV). In simpler terms, enthalpy change helps us understand how much energy is released or absorbed during a reaction.
