In the case of water, the enthalpy is a function of temperature and pressure. To determine the enthalpy of water at 220 °C and 0.01 MPa, we need to use interpolation, which is a mathematical ...

Webenthalpy is a state function. e. enthalpy change is dependent upon the number of steps in a reaction. e. What is Hess' law? Energy changes are state functions. The amount of energy depends only on the states of the reactants and the state of the products, but not on the intermediate steps. Energy (enthalpy) changes in chemical reactions are the ... WebEnthalpy (H) has to do with thermodynamics; it is a state function, at constant pressure, used in chemical and biological systems. This means that enthalpy depends only on the final energy, pressure, and volume and not the path the system took to get to the final state. This is the change in internal energy that is equal to the heat transfer ...
