Question

Diffusion occurs faster in gases than in liquids because _____.

Answer 1

Diffusion occurs faster in a gas than in liquids because in a liquid the molecules are closser together and in a gas they are farther appart

Answer 2

Step-by-step explanation:

In liquids molecules are somewhat tigthly held together compared to gas molecules. It results decrease in kinetic energy of liquid molecules

While in gases, molecules are arranged in a zigzag pattern and move freely. Hence kinetic energy is more and diffusion rate is also more for gas molecules than liquid molecules.
