Change in heat formula

WebJan 30, 2024 · ΔH = ΔU + ΔPV. 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. WebApr 4, 2024 · Heat and temperature can not be interchanged because the temperature will measure the level of hotness or coldness of material under observation. In this article, we …
