    1. The correct answer is (c) Evaporation, diffusion, expansion of gases.
      Increasing temperature enhances evaporation by providing more energy to molecules, diffusion by increasing molecular motion, and expansion of gases due to increased kinetic energy, causing gases to occupy more volume.
