Question
Can the given heat energy be completely converted to work in a cyclic process? If not, when can the heat can completely converted to work?
Solution
According to the first law of thermodynamics, work can be completely converted into heat. Since the system comes back to the initial stage, the change in the internal energy is zero. In the cyclic process, heat can flow into the system and heat flows out of the system. The net heat transferred to the system is equal to the work done by the gas.
