An ideal gas is enclosed in a cylinder with a movable piston on top of it. The piston has a mass of 8,000 g and an area of 5.00 cm2 and is free to slide up and down, keeping the pressure of the gas constant. (a) How much work is done on the gas as the temperature of 0.155 mol of the gas is raised from 15.0°C to 275°C? (J) (b) What does the sign of your answer to part (a) indicate? 1) There is no work done, by the gas or the surroundings. 2) The surroundings do positive work on the gas. 3) The gas does positive work on its surroundings.
