13 Απρ 2022 · The standard molar enthalpy of formation (or standard molar heat of formation), \ (\Delsub {f}H\st\), of a substance is the enthalpy change per amount of substance produced in the formation reaction of the substance in its standard state.
The heat of reaction, also known as enthalpy of reaction, is the enthalpy change of a chemical reaction occurring at a constant pressure. Generally, it is determined as the energy required to release or produce one mole of a substance [1-4] .
12 Ιουλ 2023 · The specific heat (C s) of a substance is the amount of energy needed to raise the temperature of 1 g of the substance by 1°C, and the molar heat capacity (C p) is the amount of energy needed to raise the temperature of 1 mol of a substance by 1°C. Liquid water has one of the highest specific heats known.
