An insulated rigid tank contains air (an ideal gas) at 500 kPa and 500 K. A valve connected to the tank is now opened, and air can escape until the pressure inside the tank is dropped to 150 kPa. The air temperature during the process is maintained constant by an electric resistance heater placed in the tank. If the volume of the tank is 5 m3, determine the work input by the electric heater to air during this process, in kJ.

A Piston-Cylinder system initially contains R-134a refrigerant at a temperature of 2.8 bar and 40°C and an initial volume of 0.1 m3. First, heat is transferred to the system by keeping the piston constant and this process is continued until the pressure is 3.2 bar. The process is then maintained by allowing the volume to change while the pressure is kept constant. At the end of this process, the temperature reaches 50°C. Assuming the state changes as if they are balanced,calculate;a) The mass of R-134a refrigerant in the system,b) The amount of heat transferred during the fixed volume process,c) The amount of heat transferred during constant pressure operation.d) Show the state changes on the P-v diagram.

A room is filled with saturated steam at 100°C. Now a 5-kg bowling ball at 25°C is brought to the room. Heat is transferred to the ball from the steam, and the temperature of the ball rises to 100°C while some steam condenses on the ball as it loses heat (but it still remains at 100°C).
