WebNov 2, 2024 · As enthalpy is a state function, change in enthalpy (ΔH) will depend on the initial and the final states of the system. ΔH = H 2 – H 1. Here, H 1 is the enthalpy of the system in the initial state and H 2 is the enthalpy of the system in the final state. So if we write the enthalpy’s formula ( H = U + PV ) in a similar form. WebTools. Sensible heat is heat exchanged by a body or thermodynamic system in which the exchange of heat changes the temperature of the body or system, and some macroscopic variables of the body or system, but …

Webthe water temperature vs. the enthalpy of the water (heat content in Btu/lb). We all know that water boils at 212ºF (atmospheric pressure at sea level). By definition, water at atmospheric pres-sure, at a temperature lower than 212ºF, is subcooled. So, we start with subcooled water at 42ºF, and begin transferring heat to it.
