Question

what is diffusion? Give one example each of diffusion in gases, diffusion in liquid and diffusion in solids.​

Answer 1

${ \pink{ \huge{ \bold{ \boxed{ {answer}}}}}}$

Diffusion is the net movement of anything from a region of higher concentration to a region of lower concentration. Diffusion is driven by a gradient in concentration. The concept of diffusion is widely used in many fields, including physics, chemistry, biology, sociology, economics, and finance.For example, when carbon dioxide diffuses into carbonated drinks then it shows diffusion of a gas into a liquid. As in liquids, molecules are held close due to slight more strong intermolecular forces of attraction as compared to gases. Hence, they take a little tie to diffuse as compared to gases.

Answer 2

Answer:

Diffusion is the net movement of anything from a region of higher concentration to a region of lower concentration.

Explanation:

gases : oxygen diffuses from the air sacs in your lungs into your blood capillaries because the concentration of oxygen is higher in the air sacs and lower in the capillary blood

solid : Alloy of metals is an example of the diffusion of a solid in another solid.

liquid : Diffusion in liquids: When substances dissolve in liquids (like salt dissolving in water) the substances spread out.
