Questions from Exercise-3 with Hints & Solutions
An ideal gas in a thermally insulated vessel at internal pressure volume and absolute temperature expands irreversibly against zero external pressure, as shown in the diagram. The final internal pressure, volume and absolute temperature of the gas are and , respectively. For this expansion

A piston filled with mol of an ideal gas expands reversibly from to at a constant temperature of As it does so, it absorbs of heat. The values of and for the process will be:

equal to:

For an ideal gas, consider only work in going from an initial state to the final state The final state can be reached by either of the two paths shown in the figure. Which of the following choice is (are) correct? [take as change in entropy and w as work done].
