enthalpy

enthalpy logo #20730(H) enthalpy change. Compare with heat. Enthalpy (H) is defined so that changes in enthalpy (H) are equal to the heat absorbed or released by a process running at constant pressure. While changes in enthalpy can be measured using calorimetry, absolute values of enthalpy usually cannot be determined. Enthalpy is formally defined as H = U + PV, where...

Enthalpy

Enthalpy logo #21000 Since enthalpy, H, consists of internal energy, U, plus the product of pressure (p) and the volume (V) of the system, which are all functions of the state of the thermodynamic system, enthalpy is a state function. The unit of measurement for enthalpy in the International System of Units (SI) is the joule, but other historical, conventional units a...

enthalpy

enthalpy logo #10444enthalpy or Helmholtz free energy (identifier H): for thermodynamic systems, it makes a difference if a process that changes U is carried out at constant volume or at constant pressure. For a process at constant volume and entropy, use internal energy U. For a process at constant pressure and entropy, enthalpy is a better choice

Enthalpy

Enthalpy logo #20840The amount of energy released or absorbed by a chemical reaction. The 'Free Enthalpy' (also called the ' Change in Gibbs Free Energy') in a reaction is the maximum amount of chemical energy available from a system that can be converted into electrical or mechanical energy and vice versa.
