Definitions from the WebTerm: Heat of FormationDefinition: The heat of formation, also known as enthalpy of formation, is the amount of heat energy released or absorbed when a compound is formed from its elements under standard conditions. Sense 1 (Chemistry): Noun: The heat of formation is a measure of the stability of a compound and can be used to determine the energy changes during chemical reactions. Example Sentence: The heat of formation for water is -285.8 kJ/mol, indicating that it releases energy when formed from hydrogen and oxygen. Sense 2 (Physics): Noun: In physics, the heat of formation refers to the amount of heat required to form a substance from its constituent particles. Example Sentence: The heat of formation of an ice cube from water vapor is 333.55 kJ/kg under normal atmospheric pressure. Sense 3 (Geology): Noun: In geology, the heat of formation refers to the heat generated during the formation of minerals or rocks. Example Sentence: The heat of formation of granite is estimated to be around 800°C due to the intense pressure and temperature during its formation deep within the Earth's crust.
