A refrigeration cycle operates between reservoirs at TH=320 KT_H = 320\text{ K} and TC=280 KT_C = 280\text{ K}. The cycle consists of four processes, and during one complete cycle, the net work input is 100 J100\text{ J} and the heat extracted from the cold reservoir is 700 J700\text{ J}. If this cycle is reversed to operate as a heat engine between the same reservoirs, what would be the heat absorbed from the hot reservoir?
