A cylinder is filled with an ideal gas and closed by a piston that moves without friction. The cylinder is placed in a large tub of cold water. The tub can be regarded as a thermal reservoir at a fixed temperature. A long time later, the piston is at rest when a student pushes downward on it and then holds the piston in place as shown.
