Question

Explian diffusion phenomena based on the states of matter.
plz help me guys tomorrow I'm having test​

Answer 1

Diffusion is the net movement of anything from a region of higher concentration to a region of lower concentration. Diffusion happens in liquids and gases because their particles move randomly from place to place. Diffusion is an important process for living things; it is how substances move in and out of cells.

Answer 2

hi,

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. It can occur in solid, liquid and gaseous states. 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.
