Q. At constant volume, for a fixed number of moles of a gas the pressure of the gas increases with rise of temperature due to

IIT JEEIIT JEE 1992States of Matter

Solution:

Average speed $=\sqrt{\frac{8RT}{\pi M}}$
i.e. at constant volume, for a fixed mass, increasing temperature increases average speeds and molecules collide more frequently to the wall of container leading to increase in gas pressure.
