Question
Which of the following will exhibit diffusion?
- Salt, sand
- Hydrogen, Oxygen
- Hydrogen, salt
- Sand, Oxygen
Hint:
Liquid and gases undergo diffusion.
The correct answer is: Hydrogen, Oxygen
- Liquid and gases undergo diffusion as the molecules are able to move randomly.
- Solids doesn't exhibit diffusion.
- So, the correct option is b.
- Salt and sand are solids.
- Hydrogen and oxygen are gases.

Passage of particles or water through the semi-permeable membrane is referred to as:
- Imbibition is a type of diffusion where the water is absorbed by the solid particles, causing an enormous increase in volume.
- A biological mechanism involving the transfer of water and other soluble nutrients from one part of the plant to another through the xylem and phloem.
