As shown in the figure, a chamber with a moveable piston and containing a monatomic ideal gas in an initial state A undergoes an isovolumetric, then an isothermal, and finally an isobaric process to complete the cycle.
When the gas is in the initial state, the volume is 3.00 L, the pressure is 5.00 atm, and the temperature is 200 K. The gas is first warmed at constant volume to a pressure of 4 times the initial value (state B). The gas is then allowed to expand isothermally to some new volume (state C). Finally, it is compressed isobarically to its initial state. Due to the nature of this problem, do not use rounded intermediate values in your calculations.
Determine values (in kJ) for Q, W, and ΔEint for the process C → A.

The gas is adiabatically and reversibly compressed to a volume of 5 L. The piston of the cylinder is locked in its place, and the insulation around the cylinder is removed. The heat-conducting cylinder is then placed in a 300-K bath. Heat from the compressed gas leaves the gas, and the temperature of the gas becomes 300 K again. The gas is then slowly expanded at the fixed temperature 300 K until the volume of the gas becomes 102 m3, thus making a complete cycle for the gas. For the entire cycle, calculate (a) the work done by the gas, (b) the heat into or out of the gas, (c) the change in the internal energy of the gas, and (d) the change in entropy of the gas.arrow_forward
