Consider a process that occurs at constant volume. The volume of a gas in a cylinder is 1.70 L, the temperature is 31.0 °C and before the position of the piston was fixed, the system was in equilibrium with an external pressure of 1.2 bar (given by the sum of a 1 bar atmospheric pressure and a 0.2 bar pressure due to a brick that rests on top of the piston). The gas is heated slowly until the temperature reaches 56.2 "C.
