Help? An explanation would be great

Three identical cylinders are sealed with pistons that are free to slide up and down the cylinder without friction. Each cylinder contains ideal gas, and the gas occupies the same volume in each case and is at the same temperature. As shown in the figure, the pistons in cylinders 1 and 3 are identical but the piston in cylinder 1 is above the gas while cylinder 3 is inverted so the piston is below the gas. The piston in cylinder 2, which is above the gas, has more mass than the other two pistons. The top surfaces of the pistons in cylinders 1 and 2, and the bottom surface of the piston in cylinder 3, are exposed to the atmosphere.

Use only "greater than" signs and "equals" signs in your ranking, such as 3>1-2 3 1-2 Answer is not case sensitive. Trom largest to smallest, in terms of the number of moles of gas inside the cylinder. Use only "greater than" signs and "equals" signs in your ranking, such as 3 1-2 1-2>3 rom largest to smallest, in terms of the number of moles of gas inside the cylinder. Use only "greater than" signs and "equals" signs in your ranking, such as 3>1-2

Explanation / Answer

Part A

In 1 and 2 cylinders pistons apply force on gas so pressure is more compare to 3 . piston of 2 have more mass so weight of this piston is more and pressure inside 2 is largest. pressure inside 1 is smaller then 2 but larger then 3.

so ranking of pressure

2>1>3

Part B

by ideal gas equation

pressure is proportional to number of moles under same temperature and volume condition. so number of moles in 2 are highest and in 3 lowest

ranking of moles

2>1>3
