Question 4
Arrange the following substances in increasing order of forces of attraction between the particles— water, sugar, oxygen.

The key to this answer is the strength of the forces of attraction in the different states of matter. Oxygen is a gas, water is a liquid and sugar is a solid.
Since sugar is a solid, the forces of attraction between the particles of sugar are strong.
Water is a liquid; the forces of attraction here are weaker than sugar.
Oxygen is a gas; the forces of attraction are the weakest in gases.
Thus, the increasing order of forces of attraction between the particles of water, sugar and oxygen is
Oxygen < Water < Sugar
