Entropy is one of the important coordinates in thermodynamics. Entropy shows the ratio of heat absorbed or rejected by temperature so that it can indicate the direction of heat flow. Entropy is useful for knowing the internal energy efficiency. Derive an equation for the change in the internal energy of a gas that satisfies the van der Waals equation of state. Assume the value of Cv satisfies the relationship: Cv=c1 + c2T, with c1 and c2 constant
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.

The following data are known for the initial state of gas: P1 = 5 bar, T1 = 500 K, and V1 =0.2 m3. When the partition is removed, the gas expands to fill the entire container, which has a total volume of 0.5 m3.
