Question

How is perfume an example of diffusion?

Answer 1

Diffusion:

1. Diffusion is the process of movement of substances from the region of their higher concentration o the region of their lower concentration.
2. Diffusion occurs in all three states of matter, solid, liquid, and gases.
3. Diffusion is fastest in gases because they have the least intermolecular force of attraction and it is slowest in solids because of the least intermolecular space and maximum intermolecular force of attraction.

Diffusion working in the case of perfume:

1. When perfume is sprayed in one corner of a room, it can soon be smelt in other corners too.
2. This happens because the particles of perfume get mixed with the particles of air due to the large intermolecular space present in the air.
3. Since perfume is either a gas or liquid thus, in both cases it can easily get mixed with the air particles.
4. This mixing of perfume particles into the air and reaching the other corner of the room is through the process of diffusion.
5. This is how diffusion works in the case of perfume.
