Question

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."
