What is definition of diffusion?

Medical Definition of diffusion

1 : the process whereby particles of liquids, gases, or solids intermingle as the result of their spontaneous movement caused by thermal agitation and in dissolved substances move from a region of higher to one of lower concentration.

Which is the best definition of diffusion?

Diffusion is a physical process that refers to the net movement of molecules from a region of high concentration to one of lower concentration. The same gas would diffuse slightly more slowly in a liquid such as water and slowest in a solid. ...

What is diffusion Class 9?

Diffusion- The mixing of a substance with another substance due to the motion or movement of its particles is called diffusion. It is one of the properties of materials. The diffusion of one substance into another substance goes on until a uniform mixture is formed. Diffusion takes place in gases, liquids and solids.

What is diffuse in chemistry?

Diffusion is the process of a substance spreading out to evenly fill its container or environment. In a solution, a concentrated solute diffuses to spread evenly in its solvent. This is the process where the particles move from high concentration to low concentration.

What is called diffusion with example?

Diffusion, process resulting from random motion of molecules by which there is a net flow of matter from a region of high concentration to a region of low concentration. A familiar example is the perfume of a flower that quickly permeates the still air of a room.

What are the 3 types of diffusion?

1 Answer. Simple diffusion, osmosis and facilitated diffusion.

What is one word diffusion?

Diffusion is the act of dispersing something, spreading it out from a central point. ... When you spray air freshener and the scent spreads from a tight space to fill a larger one, that's diffusion. In science, diffusion is a physical process of atoms or molecules moving apart within a gas or liquid.

What causes diffusion?

Diffusion is the movement of molecules from an area of high concentration of the molecules to an area with a lower concentration. ... The difference in the concentrations of the molecules in the two areas is called the concentration gradient. The kinetic energy of the molecules results in random motion, causing diffusion.

How does diffusion occur?

Diffusion, in biochemistry, refers to one of many processes by which molecules can move into and out of cells through the plasma membrane, or cross membranes within the cell, such as the nuclear membrane or the membrane that encloses mitochondria. Think of diffusion as a "drifting" movement.

What is osmosis and diffusion Class 9?

Osmosis: Osmosis is the movement of solvent particles across a semipermeable membrane from a dilute solution into a concentrated solution. ... Diffusion: Diffusion is the movement of particles from an area of higher concentration to lower concentration. The overall effect is to equalize concentration throughout the medium.

What is Plasmolysis Class 9?

Plasmolysis is defined as the process of contraction or shrinkage of the protoplasm of a plant cell and is caused due to the loss of water in the cell. Plasmolysis is an example of the results of osmosis and rarely occurs in nature.
