Question 37

Structure of Matter and Kinetic Theory

The differences observed in solids, liquids and gases may be accounted for by

  1. A.their relative masses.
  2. B.their melting points.
  3. C.the different molecules in each of them.
  4. D.the spacing and forces acting between the molecules.
Show the answer and explanation

Answer: D (the spacing and forces acting between the molecules.)

Explanation

By kinetic theory, solids, liquids and gases differ in how far apart their molecules are and how strongly they attract each other.
