Question

Which one of the following sets of phenomena would increase on raising the temperature?

• A. Diffusion, compression of gases
• B. Evaporation, condensation of gases
• C. Intermolecular distance, diffusion
• D. Diffusion, intermolecular forces

Answer 1

The correct option is C

Intermolecular distance, diffusion

As the temperature increases the kinetic energy of the molecules increases, thus reducing the intermolecular force of attraction between the molecules. The rate of diffusion increases with an increase in the movement of particles. Therefore, intermolecular distance, diffusion and expansion of gas would increase by increasing the temperature.
