Question

Arrange solid, liquid and gas on the basis of the rate of diffusion in ascending order.

• A. Solid<liquid<gas
• B. Gas<Solid< liquid
• C. Liquid<Gas< Solid
• D. Liquid< Solid< Gas

Answer 1

The correct option is A

Solid<liquid<gas

The correct order of the rate of diffusion is Solid < liquid < gas. This is due to the fact that in gaseous state particles move freely and have greater space between each other as compared to solid and liquid. So they can intermingle or diffuse easily. Similarly, liquids can diffuse easily compared to solids.
