− | In a system at a constant pressure, the change in enthalpy is equal to the amount of [[heat]] transferred by the system. But enthalpy is a [[state function]], which means that the change in enthalpy does not depend on the path of the function. Only the initial and final state of the system matters. In contrary, heat is a | + | In a system at a constant pressure, the change in enthalpy is equal to the amount of [[heat]] transferred by the system. But enthalpy is a [[state function]], which means that the change in enthalpy does not depend on the path of the function. Only the initial and final state of the system matters. In contrary, heat is a path function that is exclusively governed by the temperature gradient of the system. Thus under constant pressure, the change in heat becomes equal to the enthalpy. |
