Question

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

• A. Diffusion, evaporation, compression of gases
• B. Evaporation, compression of gases, solubility
• C. Evaporation, diffusion, expansion of gases
• D. Evaporation, solubility, diffusion, compression of gases

Answer 1

The correct option is C Evaporation, diffusion, expansion of gases

Evaporation increases as more liquid particles gain energy and come out of the liquid phase. Diffusion increases as particles gain more energy and hence are able to travel larger distances. Gases also expand on heating as energy of the particles increases.
