What is the simple definition of diffusion?

1 : the act of spreading or allowing to spread freely. 2 : the mixing of particles of liquids or gases so that they move from a region of high concentration to one of lower concentration. diffusion. noun. dif·​fu·​sion | \ dif-ˈyü-zhən \

What is diffusion scientific article?

Diffusion is the process wherein the molecules merge as a result of their kinetic energy of random motion. It occurs in liquids and gases because their molecules move randomly.

What is diffusion in life science?

Diffusion is the net movement of molecules from an area where they are at a higher concentration to areas where they are at a lower concentration. This is due to the random movement of the molecules. The difference in the concentration of a substance between two areas is called the concentration gradient .

What is an example of diffusion in science?

A tea bag immersed in a cup of hot water will diffuse into the water and change its colour. A spray of perfume or room freshener will get diffused into the air by which we can sense the odour. Sugar gets dissolved evenly and sweetens the water without having to stir it.

What is diffusion in science 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.

What is diffusion in biology class 9?

Diffusion can be described as the process of movement of molecules from a region of higher concentration to a region of lower concentration allowing the entry and exit of substances in and out of cells.

Which is the best definition of diffusion?

Diffusion can be defined as the movement of molecules from an area of their higher concentration to an area of their lower concentration. So, the correct answer is ‘Movement of molecules from an area of their higher concentration to an area of their lower concentration’.

What is diffusion in chemistry class 12?

Diffusion is the process where gaseous atoms and molecules are moved from regions of comparatively high concentration to regions of comparatively low concentration. Diffusion of gas is inversely proportional to the molecular weight of the gases.

What is diffusion class 10 science?

The movement of gases (like carbon dioxide and oxygen) from a region of high concentration to a region of low concentration through a semi permeable membrane is known as diffusion. Thus, diffusion plays an important role in gaseous exchange between the cells as well as the cell and its external environment.

What is diffusion Class 12?

What is diffusion class 10th?

Answer: Diffusion is the process of movement of molecules under a concentration gradient. The molecules move from a region of higher concentration to a region of lower concentration until the concentration becomes equal throughout. Liquid and gases undergo diffusion as the molecules are able to move randomly.

What is diffusion Class 9 Toppr?

Diffusion is a physical process that refers to the net movement of molecules from a region of high concentration to one of lower concentration. One of the main characteristics of diffusion is the movement of molecules along the concentration gradient.
