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: -Diffusion is the movement of particles from a higher concentration to a lower concentration. That’s why, when you spray perfume in the corner of a room, you will eventually smell it on the other side of the room. The perfume molecules are diffusing through the air molecules, which allows the scent to spread.

Detailed explanation-3: -Complete step by step answer: If a perfume bottle is opened at one end of a room, the odor will quickly be detected on the other side of the room. The reason behind this is diffusion. The gas present in the form of perfume is at higher concentration inside the bottle.

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: -Smells travel through the air by a process called diffusion; air particles, and the odour particles within the air, move freely in all directions. They are constantly moving and eventually they spread out through the air around them.
