Question

Assertion (A): Gases expand on heating

Reason (R):Particles of gas move away from each other on increasing the temperature of the gas​

Answer 1

Explanation:

Particles move rapidly in all directions but collide with each other more frequently than in gases due to shorter distances between particles. With an increase in temperature, the particles move faster as they gain kinetic energy, resulting in increased collision rates and an increased rate of diffusion.
