Question

The gas cylinder in (Figure 1) is a rigid container that is well insulated except for the bottom surface, which is in contact with a block of ice. The initial gas temperature is > 0C.

Part A

During the process that occurs until the gas reaches a new equilibrium, are T, W, and Q greater than, less than, or equal to zero?

Part B

Select the correct pV diagram showing the process.

Explanation / Answer

(a) Since ice is at a low temperature than 0 K so the gas temperature will decrease as a result of contact with the ice...so dT<0

W=pdV=and volume can not change in the given situation, so W=0

heat is given out to the ice from the gas Q decreases

Hope you will find the answer useful. Please rate. Cheers.

Option - A

(b) constant volume process where in pressure decreases due to decrease in temperature so the correct option is (D)
