Question

Why does diffusion occurs more quickly in case of gases than in liquids. Explain?

Answer 1

Diffusion- Diffusion is defined as a movement of a substance from the region of higher concentration to the region of lower concentration so as to spread uniformly.

• Diffusion occurs more quickly in gases than in liquids because the particles in a gas are far away from each other and move faster than the particles of a liquid.
• Thus particles in gas possess higher kinetic energy and move at high speeds.
