Definition Of Diffusion Class 9th
Simple diffusion and facilitated diffusion.
Definition of diffusion class 9th. Diffusion is a physical process that refers to the net movement of molecules from a region of high concentration to one of lower concentration. Diffusion is a natural process. Diffusion is fastest in gases and slowest in solids. It is the measurement of time that allows us to proceed in an orderly manner in this fast changing world.
Diffusion in gases is very fast. Diffusion takes place because of the movement of particles of matters. Similarly the medium in which diffusion occurs could also be in one of the three physical states.

The particles will mix until they are evenly distributed. Weight temperature length and every time is a measurement and does play a very important role in our lives. The material that diffuses could be a solid liquid or gas. Class 9 physics measurements are an integral part of our daily life.
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. The phenomenon of mixing of particles of different substances together is known as diffusion. Diffusion is the property of matter which is based on the motion of its particles. The rate of diffusion increases on increasing the temperature of the diffusing substance.
The mixing of different gases in air is a natural process that takes place continuously. Diffusion is the process of movement of molecules from a region of higher concentration to a region of lower concentration diffusion in plants diffusion is a very important process for photosynthesis where carbon dioxide from the stomata diffuses into the leaves and finally into the cells. Diffusion occurs in gases liquids and solids. Matter its definition and caracteristics.
Diffusion is a result of the kinetic properties of particles of matter. Diffusion and its applications. Diffusion can be classified into two main types. Diffusion may also be thought of as the movement of particles down a concentration gradient.
Diffusion is widely used in various fields such as biology physics chemistry etc. Main topics covered in cbse class 9 science matter in our surroundings.
