Diffusion is defined as the movement of individual molecules of a substance through a semipermeable barrier from an area of higher concentration to an area of lower concentration [34].
What is diffusion in chemistry easy?
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 in chemistry short answer?
Diffusion is the passive movement of molecules or particles from an area of higher concentration to an area of lower concentration. The concentration gradient incites them to diffuse. Since the movement is downhill, there is no chemical energy expenditure (as opposed to active transport that uses chemical energy).
What is diffusion in chemistry with example?
Perfume is sprayed in one part of a room, yet soon it diffuses so that you can smell it everywhere. A drop of food coloring diffuses throughout the water in a glass so that, eventually, the entire glass will be colored. Water diffuses into cooking noodles, making them bigger and softer.

What diffusion means?
Diffusion is defined as the movement of individual molecules of a substance through a semipermeable barrier from an area of higher concentration to an area of lower concentration [34].
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 and osmosis 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.
What is diffusion class 10th?
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 in your own words?
Diffusion is defined as a spontaneous net movement of particles down their concentration gradient or in other words from an area with greater concentration to the area with lower concentration without using any energy.
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. noun. dif·fu·sion | \ dif-ˈyü-zhən \.
What example describes diffusion?
When perfume (or air freshener, cigarette smoke, or just about any other strongly scented substance) is produced in one part of a room, it spreads to the rest through diffusion. There are fewer of the scent-producing chemicals in the further parts of the room, so the molecules naturally spread out.
What does diffusion mean in biology?
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. The difference in the concentration of a substance between two areas is called the concentration gradient .
What is diffusion Materials Science?
Diffusion is the process by which atoms move in a material. Many reactions in solids and liquids are diffusion dependent. Diffusion can be defined as the mass flow process in which atoms change their positions relative to neighbors in a given phase under the influence of thermal and a gradient.
What is diffusion quizlet?
What is diffusion ? Diffusion is the spreading of the particles of a gas, or of any substance in solution, resulting in a net movement from a region where they are of a higher concentration to a region with a lower concentration.
What is diffusion in biology kids?
Diffusion is a physical process where molecules of a material move from an area of high concentration (where there are many molecules) to an area of low concentration (where there are fewer molecules). Diffusion usually happens in a solution in gas or in a liquid. Diffusion can only work with gases and liquids.
What is diffusion answer for Class 9?
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 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 in chemistry class 7?
Diffusion is the movement of molecules from a region of their lower concentration to that of a higher one.
What is diffusion physics?
Diffusion is the movement of particles move from an area of high concentration to an area of low concentration until equilibrium is reached. A distinguishing feature of diffusion is that it results in mixing or mass transport without requiring bulk motion. The result of diffusion is a gradual mixing of material.
What is diffusion in geography?
In geography, the term diffusion refers to the spread of people, things, ideas, cultural practices, disease, technology, weather, and other factors from place to place. The three main types of this phenomenon are expansion diffusion, stimulus diffusion, and relocation diffusion.
What is diffusion in Ncert book?
No energy expenditure takes place. In diffusion, molecules move in a random fashion, the net result being substances moving from regions of higher concentration to regions of lower concentration. Diffusion is a slow process and is not dependent on a ‘living system’.
What does diffusion mean in sociology?
Sociological diffusion occurs when a social group or organization develops an innovation: a new idea or behavior. The diffusion of innovations provides insights into the process of social change: one can observe the qualities that make an innovation successfully spread and the importance of communication and networks.
What is diffusion explain with the help of an example?
Diffusion is a physical process that refers to the net movement of molecules from a region of high concentration to one of lower concentration. For instance, a gas diffuses very quickly in another gas. An example of this is the way the noxious smell of ammonia gas spreads in air.
