There is 20 g of helium in a thermally insulated cylinder under the piston. When the piston moves infinitely slowly, the gas is transferred from a state corresponding to the volume V1 = 32 • 10-3 m3 and pressure p1 = 4 • 105 Pa, to a state in which the volume V2 = 9 • 10-3 m3 and pressure p2 = 15.5 • 105 Pa. What will be the highest temperature of the gas during this process if the gas pressure is a linear function of volume?
