18 g of helium gas are placed in a cylinder with a movable piston. The gas is compressed very slowly from a state of ( p1 = 5.5atm, v1 = 32.7 × 10^3 m3) to a state of (p2 = 17atm, v2 = 11 × 10^3 m3 ). The compression is such that the system moves along a straight line in the (p,v) diagram. What is the maximum temperature reached during the compression?
