Question

The figure shows three identical chambers containing a piston and a spring with spring constant k. The chamber in a is completely evacuated, and the piston just touches its left end. In this position, the spring is relaxed. In b, the chamber contains n mol of ideal gas 1 in the space to the left of the piston, and the spring is compressed by an amount X_1. In c, the chamber contains n mol of ideal gas 2 and the spring is compressed by an amount X_2. a) Which gas exerts the greater force on the piston? [1] ideal gas 1 [2] ideal gas 2 [3] both the same [4] need more information b) Which gas exerts the greater pressure on the piston? [1] ideal gas 1 [2] ideal gas 2 [3] both the same [4] need more information c) Which gas has the larger temperature? [1] ideal gas 1 [2] ideal gas 2 [3] both the same [4] need more information d) Use the ideal gas law to find an expression for the temperature in terms of the spring constant k, the displacement X, the number of moles n, and the ideal gas constant R [1] T=kX^2/(nR) [2] T=nkX^2/(R) [3] T=kX/(n^2R) [4] none of these
