Question

what is diffusion

first and correct answer will be brainliest​

Answer 1

Explanation:

A diffusion is a process in physics. Some particles are dissolved in a glass of water. At first, the particles are all near one top corner of the glass. If the particles randomly move around ("diffuse") in the water, they eventually become distributed randomly and uniformly from an area of high concentration to an area of low concentration, and organized

Answer 2

Answer...

Definition :

Diffusion is a spontaneous movement of a substance from high concentration region to low concentration region. During this process oxygen and carbon dioxide can move across the cell Membrane

(Diffusion in biological term.)

Types

Diffusion is of two types

• Passive Diffusion

• Facilitated Diffusion.

More info

Diffusion of water is called Osmosis.

Osmosis is the movement of water molecules through plasma membrane.

Osmosis is of three types

• Hypertonic Osmosis

in this the concentration inside the cell is higher then the outside concentration

• Hypotonic Osmosis

in the the concentration inside the cell is lower then the outside concentration

• Isotonic Osmosis

in this the concentration inside and outside the cell is equal.
