chamber and thereby increases IIS VOIUme Calculate the work obtained in 1000 cycles of a reversible engine operating between 1000 K and 300 K if the heat absorbed at the higher temperature is 2.1 kJ cycle". Ifthis engine operates in the reverse direction, how much of work is needed to transfer 2.1 k of heat from the sink (300 K) ? Caleulate the free enerev chanee in the freezins of 18 g of water at 263.15 K. given that the vapour
