Let's consider a piston-cylinder system. This system is a cycle consisting of 3 phases. is passing through. 1-2: It is the compression process. There is no heat exchange during this process and the work is 58 kJ. 2-3: It is the expansion process. In this process, heat is given to the gas and work is done on the gas piston. is doing. The heat energy transferred to the system is 253 kJ and the work is 95 kJ. 3-1: By keeping the piston fixed, the gas is cooled and restored to its initial state. Find the total heat exchange of the cycle and the heat exchange during the 3-1 process.
