AI overview
Enthalpy is a measurement that combines a system's internal energy with the energy needed to make room for it at a given pressure and volume. Scientists use enthalpy to track energy changes in chemical, biological, and physical systems, especially when they occur at the constant atmospheric pressure of Earth's surface.
