Question 24

Structure of Matter and Kinetic Theory

I. Change of state II. Diffusion III. Radiation IV. Osmosis.
Which of the processes above can be explained using the kinetic theory?

  1. A.I, III and IV
  2. B.I, II and IV
  3. C.I, II, III and IV
  4. D.I, II and III
Show the answer and explanation

Answer: B (I, II and IV)

Explanation

Change of state, diffusion and osmosis all come from the motion of molecules, as the kinetic theory describes. Radiation is energy carried by electromagnetic waves, not by moving molecules.
