Liquids mix more slowly than gases. Why?

Diffusion: Diffusion is a physical process that refers to the net movement of molecules from a region of high concentration to one of lower concentration.

Diffusion in liquids is slow as compared to gases:

• The particles in the gases are more loosely packed than liquids.
• The force of attraction between the particles in the liquids is more than in gases.
• The particles of liquid have low kinetic energy than gases and therefore can not move freely.
• Hence, diffusion in liquids is slow as compared to gases.
