Detailed explanation-1: -Diffusion: Perfume particles mix with the particles of air. Due to diffusion, the particles of smelly gas are free to move quickly in all directions. So, The fragrance of perfume spreads in a room.

Detailed explanation-2: -Answer: (a) Diffusion is the mixing of a substance with another substance due to the motion of its particles. The smell of perfume spreads over a whole room is an example for diffusion.

Detailed explanation-3: -Diffusion is the movement of particles from a higher concentration to a lower concentration.

Detailed explanation-4: -Since perfume is either a gas or liquid thus, in both cases it can easily get mixed with the air particles. This mixing of perfume particles into the air and reaching the other corner of the room is through the process of diffusion. This is how diffusion works in the case of perfume.

Detailed explanation-5: -The spreading out and mixing of a substance with another substance due to the motion of its particles is called diffusion. The diffusion of gases allows the spread of the smell of a lot of things quickly. The smell of food, perfume, and fragrance of the incense stick diffuses in air.
