Question

Explian diffusion phenomenona based on the States of matter

Answer 1

Answer:

Explanation:

Diffusion is the spreading out and intermixing of one substances into another due to movement of particles. It takes place from region of high concentration to the region of low concentration till the uniform distribution is attained.

1) Diffusion occurs in Solids , Liquids and gases.

2) Diffusion in Gases:

Rate of diffusion is higher in gases due to more inter moelcular space and they move with higher Kinetic energy. 

Lighter gases diffuse faster than heavier gases.

example: Mixing of two gases.

3) Diffusion in Liquids:

Rate of diffusion in liquids is greater than solids .

example: Mixing of KMnO4  solution in water.

4) Diffusion rate in Solids :

Rate of diffusion in solids is very rarely observed .

5) factors affecting rate of diffusion:

Temperature : As temperature increases rate of diffusion increases.

Density : As density increases rate of diffusion decreases.
