Question Number 1 (25 Marks) A mass of 0.5 kg of ammonia is contained in a piston-cylinder assembly, initially at T1 = -20°C and U1 = 391.11 kJ/kg. The ammonia is slowly heated to state 2, where T2 = 20°C and P2 = 0.6 MPa, and the pressure varies linearly with specific volume during this process. From state 2, the system isºcompressed at constant pressure until the ammonia becomes a fully saturated vapor. Assume that there are no significant change...

A closed, rigid tank fitted with a paddle wheel contains 1.6 kg of air, initially at 200oC, 1 bar. During an interval of 10 minutes, the paddle wheel transfers energy to the air at a rate of 1 kW. During this time interval, the air also receives energy by heat transfer at a rate of 0.5 kW. These are the only energy transfers. Assume the ideal gas model for the air, and no overall changes in kinetic or potential energy....
