At constant volume, for a fixed number of mole of a gas, the pressure of the gas increases with rise of temperature due to
View answer and explanation
Correct option: A
Increase in average molecular speed
Option A (Increase in average molecular speed) is correct because as temperature increases, the average kinetic energy of the gas molecules increases, leading to higher speeds and more frequent/forceful collisions with the container walls, thus increasing pressure.
