Question : Consider a piston-cylinder device containing m = 1 kg of air at the initial temperature T1 = 900K and pressure P1 = 895 kPa (state 1). The ambient temperature and pressure are maintained at T (e) = 300K and P (e) = 100 kPa. The air expands in a reversible adiabatic process until the air pressure reaches the ambient pressure P(e) (the intermediate state 2). Subsequently, the system undergoes an isobaric process until it reaches the dead state DS. Part ( A) Evaluate the volume and internal energy of the air in the initial state 1, in the intermediate state 2, and in the final dead state DS. Also evaluate the temperature of the air in the intermediate state

A curious blacksmith forge 1 kg of iron then dropped it to an insulated container that contains 50 liters of water. Before dropping the iron into the insulated container, the blacksmith measures the temperature of iron and water as 500 °C and 20 °C, respectively. This curious blacksmith is always interested in thermodynamics and tries to calculate equilibrium temperature and the total entropy change because of his/her action. What will be the equilibrium temperature and the total entropy change? Is this process reversible or irreversible? (Density and specific heat of water at 20 °C are 995.10 kg/m3 and 4.16 kJ/kg.C, respectively. Assume that the specific heat capacity of iron is 0.5 kJ/kg.C)
