Correct Answer: (c) evaporation, diffusion, expansion of gases

Explanation: The rates of evaporation, diffusion, and expansion of gases increases due to an increase in temperature because when temperature increases the kinetic energy of molecules increases, which breaks or weakens the interaction between the atoms and sets the molecules free.
