Chapter 27.2, Problem 2bTH
One mole of an ideal gas is confined to a container with a movable piston. The questions below refer to the processes shown on the PV diagram at right. Process I is a change front state X to state Y at constant pressure. Process II is a change from state W to state Z at a different constant pressure.
b. In the two processes, does the piston move inward, move outward, or not move? Explain.

B.Compare the temperature outside (surroundings) and inside (system) the bottle before pouring the boiling water into the bucket.
C.Compare the temperature outside (surroundings) and inside (system) the bottle after pouring the boiling water into the bucket.
Part B
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.
Starting from equilibrium at point 0, what point on the pV diagram will describe the ideal gas after the following process?
"Immerse the container into a large water bath at the same temperature, and very slowly push the piston head further into the container."
