Question

diffusion occurs the fastest in gases why​

Answer 1

Diffusion in gases is very fast. This is because the particles in gases move very quickly in all directions.

The rate of diffusion of a gas, however, depends on its density. Light gases diffuse faster than heavy gases.

Example: When we light an incense stick (agarbatti) in a corner of our room, its fragrance spreads in the whole room very quickly due to the diffusion of its smoke into the air.

Answer 2

Because gases flow easily
