Question

Which of the following is true regarding the process of diffusion?

• A. It occurs when the concentration of molecules remains constant.
• B. It occurs from a region of higher concentration to a region of lower concentration.
• C. It occurs from a region of lower concentration to a region of higher concentration.
• D. All of the above

Answer 1

The correct option is B

It occurs from a region of higher concentration to a region of lower concentration.

The process of diffusion is defined as the movement of molecules of matter from a region of higher concentration to a region of lower concentration. In other words, the process of diffusion occurs when there is a difference in concentration and the movement of molecules occur from a region of higher concentration to a region of lower concentration.
