On the other hand most of the heat added is for the enthalpy of vaporization (i.e. for the phase change). The enthalpy of a system is measured by the sum of the internal energy and the product at constant pressure and volume. H = E + PV ………………….. Enthalpy is an extensive quantity, it depends on the size of the system, or on the amount of substance it contains. The SI unit of enthalpy is the joule (J).

We understand the mining business and the criticality of the investment decisions made. 2010-02-12 Enthalpy of Formation (Δ f H° or Δ formation H°):. The change in enthalpy of a chemical reaction at a given temperature and pressure, when one mole of the substance is formed from its constituent elements in their standard states is called the heat of formation. 2016-05-13 Enthalpy definition is - the sum of the internal energy of a body or system and the product of its volume multiplied by the pressure. Enthalpy In the previous section we defined enthalpy as being the heat transferred during a constant pressure process. - Home -

Enthalpy / ˈɛnθəlpi / (listen) is a property of a thermodynamic system, defined as the sum of the system's internal energy and the product of its pressure and volume, H = U + pV. It is a convenient state function standardly used in many measurements in chemical, biological, and physical systems at a constant pressure.
