Answer:
Diffusion Definition
“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?
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. The molecules move from a region of higher concentration to a region of lower concentration, down the concentration gradient, until the concentration equalizes throughout the medium.
For instance:
Take a beaker filled with water. Add a few crystals of copper sulfate carefully and leave the unit undisturbed for some time. We can observe that the water in the beaker is uniformly coloured. In this experiment, both copper sulfate and water diffuse independently. Therefore, the concentration gradient would be nothing other than the process by which particles known by the name of solutes travels through a solution from a higher particle numbered area to a lower-numbered area.
Factors Affecting Diffusion
There are a few factors that affect the process of diffusion, which individually and collectively alters the rate and extent of diffusion. These factors include:
Temperature.
Area of Interaction.
Size of the Particle.
The steepness of the concentration gradient.
Examples of Diffusion
A teabag 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.
As we lit the incense stick, its smoke gets diffused into the air and spreads throughout the room.
Answer:
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.
Explanation:
Diffusion: The phenomenon of mixing of particles of different substances together is known as diffusion. Diffusion takes place because of the movement of particles of matters. Diffusion is a natural process. The mixing of different gases in air is a natural process that takes place continuously.
This kind of proliferation is known as spatial diffusion. The three main types of this phenomenon are expansion diffusion, stimulus diffusion, and relocation diffusion.
