Basic Thermodynamic Processes

The word 'thermodynamics' can be divided into two words, 'thermo' and 'dynamics'. The word thermo deals with the heat and thermal phenomenon, whereas dynamics deals with forces or external agent that drives the heat flow or aids in the motion of heat.

4. What is the second law of thermodynamics, give its Clausius and Kelvin-Planck statements and justify on their basis why a perpetual motion machines that extracts heat from ambient environment to do work is not feasible. What is difference between reversible and an internally reversible process, and why are most actual processes considered irreversible. Numerical:
Is energy added to the gas by heating or removed by cooling in each cycle? Support your claim in a coherent paragraph-length response that qualitatively compares the amounts of energy added to the gas by heating or removed by cooling in the two cycles and refers to the work done on the gas and the change in internal energy of the gas.
2. . Two reversible engines A and B operate in series. Engine A receives heat at 500 °C and rejects heat to a reservoir at temperature T. Engine B receives the heat rejected by the first engine and, in turn, rejects heat to a thermal reservoir at 20 °C. Determine the temperature T (°C) for the following situations: (i). The work outputs of the two engines are equal (ii). The thermal efficiencies of the two engines are equal
