Gases diffuse faster compared to liquids because of the reason that the liquid molecules_________________?
Correct answer: C. Are held together by stronger inter-molecular forces
- A. Have no definite shape
- B. Move faster
- C. Are held together by stronger inter-molecular forces
- D. Are heavier
Explanation
Liquid molecules are more strongly held by intermolecular forces, which restricts their movement and lowers diffusivity. Gas molecules are farther apart and experience weaker cohesive forces, so diffusion is faster.
