What is diffusion in science easy?
Diffusion is the movement of a substance from an area of high concentration to an area of lower concentration . Diffusion occurs in liquids and gases when their particles collide randomly and spread out. Diffusion is an important process for living things – it is how substances move in and out of cells.
What is a diffusion in very short definition?
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.
What is diffusion scientific article?
Diffusion is the net movement of anything (for example, atom, ions, molecules) from a region of higher concentration to a region of lower concentration.
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 10?
“Diffusion is the movement of molecules from a region of higher concentration to a region of lower concentration down the concentration gradient.”
What is simple diffusion in biology class 10?
Hint: Simple diffusion can be described as a process in which the movement of substances occurs via a semipermeable membrane or in a solution without any help from transport proteins. The examples of simple diffusion can be bacteria delivering small nutrients, movement of water and oxygen into the cytoplasm.
What is diffusion in science class 8?
Diffusion is the movement of molecules from a region of higher concentration to a region of lower concentration down the concentration gradient.
What is diffusion in biology class 11?
Diffusion. The movement of molecules from regions of higher concentration to regions of lower concentration is called diffusion. Movement by diffusion is passive. Diffusion rates are affected by the gradient of concentration, the permeability of the membrane separating them, temperature, and pressure.
What is diffusion class 9th answer?
Complete answer: 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.
What is diffusion Class 9 short 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.
