The meaning of ENTHALPY is the sum of the internal energy of a body or system and the product of its volume multiplied by the pressure.
Related to Standard enthalpy: Standard enthalpy change of reactionen·thal·py (ĕn′thăl′pē, ĕn-thăl′-) n. pl. en·thal·pies Symbol H A thermodynamic function of a system, equivalent to the sum of the internal energy of the system plus the product of its volume multiplied ...
a body, there is a change in its volume. The alternate solution is to carry out the reaction at a constant pressure – in flasks and test tubes. Hence, there is a need for another state function which defines the change in internal energy at a constant pressure. The concept of enthalpy...
