An insulated, rigid tank whose volume is 0.5 m³ is connected by a valve to a large vessel holding steam at 40 bar, 480°C. The tank is initially evacuated. The valve is opened only as long as required to fill the tank with steam to a pressure of 20 bar. Determine: (a) the final temperature of the steam in the tank, in °C, the final mass of the steam in the tank, in kg, and (b) the amount of entropy produced, in kJ/K.

Oxygen (molar mass 32 kg/kmol) expands reversibly in a cylinder behind a piston at a constant pressure of 3 bar. The volume initially is 0.01 m and finally is 0.03 m; the initial temperature is 18.32 C. Calculate the mass of oxvgen with the correct unit to four decimal places. Assume oxygen to be a perfect gas and take the specific heat at constant pressure as = 0.917kj/kg Kand molar gas constant as = 8,314 J / kmol K
