explain diffusion phenomenal based on the states
Answers
Answer:
Diffusion of a gas or liquid is the process of spreading through or into a surrounding substance by mixing with it. It takes place from the region of high concentration to the region of low concentration till the uniform distribution is attained.
Explanation:
Diffusion is a mass transfer phenomenon that causes the distribution of a chemical species to become more uniform in space as time passes.
Diffusion is the property of matter which is based on the motion of its particles. Diffusion occurs in gases, liquids and solids. Diffusion is fastest in gases and slowest in solids.
The phenomena of diffusion in three different states are as explained below:
• Diffusion in gaseous state: Rate of diffusion is higher in gases due to more inter molecular space, and they move with higher Kinetic energy. Lighter gases diffuse faster than heavier gases.
Example: Mixing of two gases.
• Diffusion in a liquid state: Rate of diffusion in liquids is greater than solids.
Example: Mixing of the KMnO4 solution in water.
• Diffusion in the solid state: Rate of diffusion in solids is very rarely observed.
