An ideal gas is compressed from a volume of V, = 5.50 L to a volume of V, = 3.00 L while in thermal contact with a heat reservoir at T = 295 K as in the figure below. During the compression process, the piston moves down a distance of d = 0.125 m under the action of an average external force of F = 10.0 kN. A cross section of a cylinder whose base rests on a surface labeled T. A disk representing a movable piston is shown in two locations. On the upper location is an arrow labeled F that points downward. The vertical distance between the two piston locations is d. (a) Find the work done on the gas. kJ (b) Find the change in internal energy of the gas. kJ (c) Find the thermal energy exchanged between the gas and the reservoir. kJ (d) If the gas is thermally insulated so no thermal energy could be exchanged, what would happen to the temperature of the gas during the compression? O The temperature would increase. O The temperature would remain constant. O The temperature would decrease.

Answers (~1.9kJ, ~1.1kJ, ~4kJ) The figure to the right shows a gas contained in a vertical piston-cylinder assembly. A vertical shaft with a cross- sectional area of 1.0 cm² is attached to the top of the piston. The total mass of the piston and shaft is 35 kg. While the gas is slowly heated, the internal energy of the gas increases by 0.25 kJ, the potential energy of the piston-shaft combination increases by 0.5 kJ, and a force of 1300 N is exerted on the shaft as shown in the figure. The piston and cylinder are both good insulators and friction between them is negligible. The local atmospheric pressure is 1 bar and g = 9.81 m/s².
