A sample of gas is in a cylinder of fixed volume.At 30.0^°C its internal pressure is 3200. torr.What will be its pressure at 12.0^°C?

Question

Quizplus · Accepted Answer

The pressure of a gas at constant volume and temperature is directly proportional to the number of moles of gas present. Therefore, the pressure at 12.0°C will be the same as the pressure at 30.0°C. Thus, the pressure at 12.0°C will also be 3200 torr. The only answer choice that is closest to 3200 torr is D) 3010 torr, which is the best choice.
