Web7 okt. 2024 · How is enthalpy used in real life? Change in enthalpy can apply to refrigerators and hand warmers. In a fridge, refrigerants such as Freon are evaporated. The enthalpy of vaporization (liquid to gas energy change) is equivalent to the coldness of your food. Some people use chemical heat packs (hand warmers) outside. WebEnthalpy change Enthalpy change is the standard enthalpy of formation. We have determined it for a vast number of substances. In any given chemical reaction, the reactants undergo chemical changes and combine to form different products. For any such reaction, we represent the enthalpy change as Δ r H. We term it as the reaction enthalpy.
