Sample questions

1. Which of the following is NOT a bulk property of matter?

   1. Density
   2. Viscosity
   3. Mass
   4. Color
   Show answer

   Answer: D. Color

   Color is an intensive property, depending on the substance itself rather than the amount. Density, viscosity, and mass are all extensive properties that change with the amount of substance.

2. What is surface tension?

   1. The force that causes the surface of a liquid to contract
   2. The force that causes a liquid to spread out
   3. The force that causes a liquid to boil
   4. The force of attraction between molecules in a liquid
   Show answer

   Answer: A. The force that causes the surface of a liquid to contract

   Surface tension is the tendency of liquid surfaces to shrink into the minimum surface area possible.

3. What are adhesive forces?

   1. Forces of attraction between molecules of the same substance
   2. Forces of attraction between molecules of different substances
   3. Forces of repulsion between molecules of the same substance
   4. Forces of repulsion between molecules of different substances
   Show answer

   Answer: B. Forces of attraction between molecules of different substances

   Adhesive forces are intermolecular forces of attraction between unlike molecules.

4. Describe the process of osmosis.

   1. The movement of solvent molecules across a semipermeable membrane from a region of lower solute concentration to a region of higher solute concentration
   2. The movement of solute molecules across a semipermeable membrane from a region of higher solute concentration to a region of lower solute concentration
   3. The movement of solvent molecules across a permeable membrane
   4. The movement of any molecule across a membrane
   Show answer

   Answer: A. The movement of solvent molecules across a semipermeable membrane from a region of lower solute concentration to a region of higher solute concentration

   Osmosis is the movement of water molecules across a selectively permeable membrane from a region of higher water concentration (lower solute concentration) to a region of lower water concentration (higher solute concentration).

5. Explain the concept of elevation in boiling point.

   1. The increase in boiling point of a liquid when a non-volatile solute is added
   2. The decrease in boiling point of a liquid when a non-volatile solute is added
   3. The increase in boiling point of a liquid when a volatile solute is added
   4. The decrease in boiling point of a liquid when a volatile solute is added
   Show answer

   Answer: A. The increase in boiling point of a liquid when a non-volatile solute is added

   Adding a non-volatile solute to a solvent increases the boiling point of the solution, a phenomenon known as boiling point elevation.
