  1. Boiling point

  2. Vapour pressure

  3. Osmosis

  4. Surface tension
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Colligative properties are properties of solutions that depend upon the ratio of the number of solute particles to the number of solvent molecules in a solution, and not on the type of chemical species present. The concentration of solutes will affect the boiling point, vapour pressure and osmotic properties, but surface tension is a physical property of water.
