Question

Give reason gases undergo diffusion very fast

Answer 1

The force of attraction in the gas is quite low; therefore, the molecules have complete freedom to move around.

Gasses easily take the shape of the vessels and tend to occupy free space.

Hence, they undergo diffusion quite fast. Whereas, solids are bounded by strong force of attractions and so, there is no space to facilitate the process of diffusion. 

Answer 2

Answer:

Gaseous particles undergoes diffusion as they have kinetic energy . Due to high speed of particles and large space between them , thus gas show the property of diffusion.
