When the ambient temperature is 300K, the cold energy of Qo=1000kJ is extracted from the cold source at 250K. What is the cold exergy contained in Qo? An engine works between two heat sources of 600K and 300K. When it acquires heat from the hot heat source of 1000J, the work done outward is 400J. Calculate the perfection degree of the system.
