A rigid closed tank is full of oxygen at 120 kPa and 25 C. The mass of oxygen in the tank is 1.8
kg. A stirring device introduces 150 kJ of work and there is heat loss to the surroundings in the
amount of 45 kJ. Find the final temperature in Celsius and pressure in kPa.
Assume specific heats constant at room temperature (300 K).

Air is contained in a rigid, well-insulated container of volume 3 m3. The air undergoes a process from an initial state with a pressure of 200 kPa and temperature of 300 K. During the process, the air receives 720 kJ of work from a paddle wheel. Model the air as an ideal gas with constant specific heats. Evaluate the specific heats at 300 K. Neglect changes in kinetic energy and potential energy. Determine the mass of the air in kg,...

An initially empty, well insulated, rigid tank with a volume of 2 m3 is fitted with a mixing device. The tank has two inlets and zero outlets. One inlet is water at 1 MPa and 600◦C while the other is saturated liquid water. Both enter the tank slowly. If the amount of work done by the mixing device is 300 kJ, what must the temperature of the saturated liquid water be if the same mass is added through both inlets...
