Question

A gas is filled in a cylinder fitted with a piston at a definite temperature and pressure. Explain on the basis of kinetic theory, the pressure of the gas increases by raising its temperature.

Answer 1

On raising the temperature, the average velocity of the gas moleacules increases. Therefore, larger number of molecules collide with the walls of the cylinder and hence greater momentum os transferred per second to the walls. Due to both these reasons, the pressure increases as `P=mnC^(2)//3V`.
