Carbon dioxide (CO2) fills a closed, rigid tank fitted with a paddle wheel, initially at 80°F, 50 lbf/in2, and a volume of 2.2 ft3. The gas is stirred until its temperature is 500°F. During this process heat transfer from the gas to its surroundings occurs in an amount 2.6 Btu. Assume ideal gas behavior, but do not assume constant specific heats. Kinetic and potential energy effects can be ignored. Determine the mass of the carbon dioxide, in lb, and the work, in Btu.
Thermodynamics Answer the following problem with complete solutions. Write legibly A gas goes through the following thermodynamic processes: A to B: constant-temperature compression; B to C: constant-volume cooling; C to A: constant-pressure expansion.

As shown, a piston-cylinder assembly contains 5 g of air holding the piston against the stops. The air, initially at 3 bar, 600 K, is slowly cooled until the piston just begins to move downward in the cylinder. The air behaves as an ideal gas, g = 9.81 m/s2, and friction is negligible. Sketch the process of the air on a p–V diagram labeled with the temperature and pressure at the end states. Also determine the heat transfer, in kJ, between the air and its surroundings.

Thermodynamics A Piston-Cylinder system initially contains R-134a refrigerant at a temperature of 2.8 bar and 40 C, and its initial volume is 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 maintained by allowing the volume to change. At the end of this process, the temperature reaches 50C. Assuming the state changes as if balanced, calculate the following: a)He amount of heat transferred during constant pressure operation b)Show the state changes on the P-v diagram.

Referring to the figure shown below, water contained in a piston-cylinder assembly, initially at 1.5 bar and quality of 20%, is heated at constant pressure until the piston hits the stops. Heating then continues until the water is a saturated vapor. The initial height,L1L1, is 0.05 m and the change in height, L2L2, is 0.02 m.
Air is contained in a piston/cylinder device at an initial state where the volume is 1.7 m3, temperature is 250 K, and pressure is 454 kPa. In a portion of an engine cycle, air goes through the following two sequential processes: Process 1-2: It is heated while the system is allowed to expand at constant pressure, until the volume increases by 55%. Process 2-3: It is heated further to maintain a constant temperature while the volume increases by 55% again. To simplify this problem, you can treat air as an ideal gas with constant specific heats. a.) On your paper, draw these processes on a P-V diagram. Label states 1, 2, and 3. b.)
