QUESTION 1 An ideal monatomic gas is confined in a container with a moveable piston. 30,000 J of thermal energy are added to the gas. The gas does 10,000 J of work while expanding. The change in internal energy of the gas is ? 10,000 J ? 20,000 J ? 30,000 J ? 40,000 J ? Cannot know unless we know how many moles of gas are in the container QUESTION 2 An ideal monatomic gas is confined in a container with a moveable piston. 10,000 J of thermal energy are removed from the gas. Then 20,000 J of work is done on the gas by compressing it. The change in internal energy of the gas is ? -30,000 J ? 10,000 J ? 20,000 J ? 30,000 J ? Cannot know unless we know how many moles of gas are in the container

          QUESTION 1

? -30,000 J
? 10,000 J
? 20,000 J
? 30,000 J
? Cannot know unless we know how many moles of gas are in the container
