1. Which statement correctly describes the shape and volume of a liquid?

  1. Fixed shape and fixed volume
  2. No fixed shape but fixed volume
  3. No fixed shape and no fixed volume
  4. Fixed shape but no fixed volume
Show answer

Answer: B

A liquid has a definite volume, but its shape adjusts to match the container holding it.

2. What is the process called when water vapor in the atmosphere turns directly into frost (solid ice) on freezing cold surfaces?

  1. Sublimation
  2. Deposition
  3. Evaporation
  4. Melting
Show answer

Answer: B

Deposition is the reverse of sublimation, where a gas converts directly into a solid upon releasing heat energy.

3. Why can gases be compressed easily into smaller containers, whereas solids cannot?

  1. Gas particles move slowly
  2. There are large empty spaces between gas particles
  3. Gas particles have strong attraction forces
  4. Gas particles have fixed positions
Show answer

Answer: B

Gas particles are spread far apart, leaving substantial space between them that allows compression when external pressure is applied.

4. Which of the following changes of state involves the release (loss) of heat energy?

  1. Melting
  2. Boiling
  3. Freezing
  4. Sublimation
Show answer

Answer: C

Freezing requires liquid to lose thermal energy (cool down) to solidify.

5. Which property of matter is considered a chemical property?

  1. Boiling point
  2. Flammability
  3. Electrical conductivity
  4. Solubility
Show answer

Answer: B

Flammability describes how a substance reacts with oxygen to form new chemical products, making it a chemical property.

6. Which process describes the direct transformation of a solid into a gas without turning into a liquid first?

  1. Evaporation
  2. Condensation
  3. Sublimation
  4. Deposition
Show answer

Answer: C

Sublimation is the process where a solid absorbs heat energy and transitions directly into gas.

7. Which physical property measures the temperature at which a liquid rapidly transitions into a gas throughout its entire volume?

  1. Melting point
  2. Boiling point
  3. Freezing point
  4. Condensation point
Show answer

Answer: B

The boiling point is the specific temperature at which liquid turns into gas throughout the bulk liquid.

8. How do particles move inside a solid material?

  1. They slide across each other freely
  2. They move rapidly in random straight paths
  3. They vibrate and rotate about fixed positions
  4. They remain completely motionless
Show answer

Answer: C

Because of strong attractive forces, solid particles cannot translate position freely; they only vibrate and rotate in place.

9. What happens to the temperature of a substance while it is actively undergoing a change of state (e.g., melting)?

  1. It increases steadily
  2. It decreases rapidly
  3. It remains constant
  4. It fluctuates unpredictably
Show answer

Answer: C

During a state transition, temperature stays constant because absorbed heat energy is consumed to overcome inter-particle forces rather than increase temperature.

10. Which material characteristic measures its ability to allow electric current to pass through it?

  1. Heat conductivity
  2. Electrical conductivity
  3. Solubility
  4. Density
Show answer

Answer: B

Electrical conductivity determines how easily electric current flows through a material.
