Question

Which of the following will exhibit diffusion?

  1. Salt, sand
  2. Hydrogen, Oxygen
  3. Hydrogen, salt
  4. Sand, Oxygen

hintHint:

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.
