One-tenth kg of a gas in a piston-cylinder assembly undergoes a Carnot power cycle for which the isothermal expansion occurs at 800K. The change in specific entropy of the gas during the isothermal compression which occurs at 400K, is -25Kj/Kg.K. Determine (a) the net work developed per cycle, in kJ, and (b) the thermal efficiency.
