explain an activity to prove diffusion occurs in gases with neate diagram
Answers
Answer:
Diffusion is the movement of molecules from a region of higher concentration to a region of lower concentration down the concentration gradient.”
Read on to explore what is diffusion and the different types of diffusion.
What is Diffusion?
Diffusion is the process of movement of molecules under a concentration gradient. It is an important process occurring in all living beings. Diffusion helps in the movement of substances in and out of the cells. 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.
Diffusion
Example:
Take water in a beaker. Add a few copper sulfate crystals at one place and leave it as it is for some time without disturbing it. After some time we can see that beaker contains a uniformly coloured solution. Here, both water and copper sulfate diffuse independently. With this experiment, we can infer that solutes move from a higher concentration to the lower concentration in a solution.

Types of Diffusion
Diffusion is widely used in various fields such as biology, physics, chemistry, etc. Diffusion can be classified into two main types: Simple diffusion and facilitated diffusion.
