Question

Why is the rate of diffusion faster in gases than liquids?

Answer 1

Because gas molecules have more kinetic energy and are smaller than liquid molecules. diffusion in liquids is slower because the particles in a liquid move more slowly. it happens faster if the temperature is increased.

Answer 2

The molecules of gas have more kinetic energy than liquid molecules and are smaller. ... The distance between the constituent particles in gases becomes greater than in liquids, resulting in diffusion faster in gases than in liquids. Therefore, gas particles have higher kinetic energy and travel more rapidly.
