A polyatomic ideal gas (CV = 3R) expands during the process described in the problem (The states of a mole of an ideal gas during a certain process are depicted by points lying on a straight line connecting points A and B (figure): VA = 0, PA = P0; VB = V0, РB = 0. Find the dependence of gas temperature on volume; determine the maximum gas temperature during such a process.). In which areas is heat supplied to the gas, and in which areas is it removed from it?
