4. For the system shown in the adjacent figure, the gas in the piston/cylinder is at equilibrium initially at 180°C and the surroundings are at 20°C. Because the cylinder is thermally conductive, as the gas exchanges heat with the surrounding it cools down, and finally equilibrates with the surrounding temperature. In the schematic, please ignore the presence of the light gray box to the left of the piston rod. 3 kg 20 °C gas 180 °C a. What happens to the pressure and volume of the gas during this process? Qualitatively explain. b. If you assumed ideal gas behavior, can you quantify the percentage by which the gas volume changes between the initial and the final state?

Please do not solve the question in the 2nd image. From image 1, Total entropy change: Ssystem + Ssurrounding = Sisolated What does it mean by Ssystem and Ssurrounding? Able to explain it using the question shown in the 2nd image? Is the question asking to find Ssystem or Ssurrounding? i am able to obtain the answer by finding the Rate of Entropy change in the high Temperature side and low temperature side. But i do not know whether it is the entropy for the system or surrounding.

A container holds a sample of ideal gas in thermal equilibrium, as shown in the figure. (Figure 1) One end of the container is sealed with a piston whose head is perfectly free to move, unless it is locked in place. The walls of the container readily allow the transfer of energy via heat, unless the piston is insulated from its surroundings. Refer to the pV diagram presented to answer the questions below. (Figure 2) In each case, the piston head is initially unlocked and the gas is in equilibrium at the pressure and volume indicated by point 0 on the diagram. Starting from equilibrium at point 0, what point on the pV diagram will describe the ideal gas after the following process? "Lock the piston head in place, and hold the container above a very hot flame."
