Web all pure elements in their standard state (e.g., oxygen gas, carbon in all forms, etc.) have a standard enthalpy of formation zero. Such a separation requires energy. But an element formed from itself means no heat change, so its enthalpy of formation will be zero. O = a degree signifies that it's a standard enthalpy change. Web the standard enthalpy of formation is a measure of the energy released or consumed when one mole of a substance is created under standard conditions from its pure elements. Web all pure elements in their standard state (e.g., oxygen gas, carbon in all forms, etc.) have a standard enthalpy of formation zero. The figures and tables below shows how water enthalpy and entropy changes with temperature (°c and °f) at water saturation pressure. Web the standard enthalpy of formation is then determined using hess's law. Follow the links for definitions of the terms specific enthalpyand entropy.
