A cylinder fitted with a frictionless piston contained an ideal gas, with a volume of 23 m³, a temperature of 17 °C, and a pressure of 2 bar. It asks to raise its pressure to 6 bar by two different reversible processes: Heating under constant volume and cooling under polytropic compression with n= 1.3. Determine the work and heat as well as entropy change of ideal gas for two processes. Knowing that: Cp = 0.293 kJ/kg.K Cv = 0.24 kJ/kg.K.

A unit mass of an ideal gas at temperature T undergoes a reversible isothermal process from pressure P1 to pressure P2 while losing heat to the surroundings at temperature T in the amount of q.

A frictionless piston-cylinder assembly initially contains saturated liquid water at a pressure of 200 kPa. Then, 450 kJ of heat transfer occurs from a source with a temperature of 500 0C to water and some of the water evaporates at constant pressure. Show whether this state change is feasible or not by considering the increase of entropy principle.
Heat flows through a wall of a house at a steady-state on a day when the temperature of the outdoor air is 1°C and the air inside the house is maintained at 23°C. The temperatures of the inner surface of the wall is 4°C cooler than indoor air temperature. And the temperature of the outer surface of the wall is 2°C warmer than the outdoor air temperature. The rate of heat transfer through the wall is 900W. Determine the rate of total entropy generation associated with this heat transfer process (in W/K).
A piston is inserted into a cylinder causing the pressure in the air to change from 50 to 4000 kPa while the temperature remains constant at 27°C. To accomplish this, heat transfer must occur. Determine the entropy change.
