Question

For an ideal gas, each of the following unquestionably leads to an increase in the pressure of the gas, except one. Which one is it? A. Increasing the temperature and decreasing the volume, while keeping the number of moles of the gas constant. B Increasing the temperature, while keeping the volume and the number of moles of the gas constant. C Decreasing the volume, while keeping the temperature and the number of moles of the gas constant. D Increasing the temperature, volume, and the number of moles of the gas. E Increasing the number of moles of the gas, while keeping the temperature and the volume constant.

Explanation / Answer

The answer is (D)increasing the temperature volume and number of moles in the gas. This is because gas equation always holds PV=nRT , so if T and n both are increasing it is possible that V would increase so much that there would be no need to increase P
