Detailed explanation-1: -For example, when someone sprays perfume and the “scent molecules” gradually spread out in the room so that everyone can smell the perfume-that’s diffusion. Both are examples of passive transport, which means they occur without the input of any additional energy.

Detailed explanation-2: -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-3: -When you spray perfume in one spot, the scent travels beyond that spot because the molecules in the perfume are diffusing from where they are more concentrated to where they are less concentrated. In another word, the molecules are spreading out.

Detailed explanation-4: -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-5: -The particles of the perfume intermixes with the air. As the rate of diffusion is very high in gases, they spread throughout the room in very less time.
