Zemansky defines Heat as : When a closed system whose surroundings are at a different temperature and on which diathermic work may be done undergoes a process, then the energy transferred by non mechanical means, equal to the difference between the change in internal energy and the diathermic work is called heat. ##Q= \Delta U - W##(diathermic).
But the First Law of Thermodynamics states : ## Q = \Delta U + W##
Is the discrepancy because for diathermic work, ## W = -W##?
