Question

Gas cylinders with the mass (or number of molecules) of He gas have various volumes and temperatures, which are given in the diagram below. All of the containers are made of the same material. Rank these containers from the highest to lowest on the basis of their gauge pressures. A : 200K 2L B : 300K 15L C : 400K 5L D : 300K 10L E : 200K 4L F : 500K 10L Highest 1........2........3.........4.........5.........6........Lowest Please carefully explain your reasoning. How sure were you of your ranking? Basically Guessed? Sure? or very sure?

Explanation / Answer

PV=n*R*T P=n*R*T/V so the ranking is:A C E F D B
