(Symbol H), pl. -pies. 焓
A thermodynamic function of a system, equivalent to the sum of the internal energy of the system plus the product of its volume multiplied by the pressure exerted on it by its surroundings.
━━ n. 【物】エンタルピー.
The bond energy in a biochemical reaction.
In thermodynamics and
molecular chemistry, the enthalpy or heat content (denoted as H or ΔH, or rarely as χ) is a quotient or description of thermodynamic potential of a system, which can be used to calculate the "useful" work obtainable from a closed thermodynamic system under constant pressure.
The term enthalpy is composed of the prefix en-, meaning to "put into", plus the Greek word -thalpein, meaning "to heat", although the original definition is thought to have stemmed from the word, "enthalpos" (ἐνθάλπος). It is often calculated as a differential sum, describing the changes within exo- and endothermic reactions, which minimize at equilibrium.
