If temperature and pressure remain constant through the process and the work is limited to pressure-volume work, then the enthalpy change is given by the equation: ΔH = ΔU + PΔV. Also at constant pressure the heat flow ( q) for the process is equal to the change in enthalpy defined by the equation: ΔH = q.
