Matter and Energy Practice Tests

These Grade 10 Science practice tests develop matter classification, states of matter, density, phase changes, heat transfer, kinetic and potential energy, conservation of energy, and basic thermal calculations.

Skills covered

  • Classifying matter, pure substances, states of matter, plasma, physical properties, mass, volume, and density
  • Explaining melting, freezing, vaporization, condensation, sublimation, deposition, heating curves, and phase-change energy
  • Distinguishing conduction, convection, radiation, thermal equilibrium, insulators, and conductors
  • Comparing kinetic, potential, chemical, exothermic, and endothermic energy changes
  • Using density ρ = m/V and thermal-energy relationships such as q = mcΔT with correct units

How to use these practice tests

Identify whether the question describes particles, energy, or a measurable property. Keep mass, volume, temperature, and energy units visible, and distinguish average particle energy from total thermal energy.

Correct answer: A

The correct answer is ρ = m/V.

  1. Identify the matter or energy concept: Determine whether the question asks about a property, state, phase change, heat transfer, energy form, conservation, density, or specific heat.
  2. Use the relationship or observation: Density equals mass divided by volume.
  3. Check the unit and conclusion: The correct answer is ρ = m/V.

Density equals mass divided by volume.

2. QuestionMultiple choice

A sample has a mass of 20 g and a volume of 5 mL. What is its density?

Please select an answer first.

Correct answer: B

The correct answer is 4 g/mL.

  1. Identify the matter or energy concept: Determine whether the question asks about a property, state, phase change, heat transfer, energy form, conservation, density, or specific heat.
  2. Use the relationship or observation: Divide mass by volume: 20 g ÷ 5 mL = 4 g/mL.
  3. Check the unit and conclusion: The correct answer is 4 g/mL.

Divide mass by volume: 20 g ÷ 5 mL = 4 g/mL.

3. QuestionMultiple choice

What is the mass of a 3 mL sample with a density of 2 g/mL?

Please select an answer first.

Correct answer: C

The correct answer is 6 g.

  1. Identify the matter or energy concept: Determine whether the question asks about a property, state, phase change, heat transfer, energy form, conservation, density, or specific heat.
  2. Use the relationship or observation: Use mass = density × volume: 2 g/mL × 3 mL = 6 g.
  3. Check the unit and conclusion: The correct answer is 6 g.

Use mass = density × volume: 2 g/mL × 3 mL = 6 g.

4. QuestionMultiple choice

What is the volume of a 10 g sample with a density of 2 g/mL?

Please select an answer first.

Correct answer: D

The correct answer is 5 mL.

  1. Identify the matter or energy concept: Determine whether the question asks about a property, state, phase change, heat transfer, energy form, conservation, density, or specific heat.
  2. Use the relationship or observation: Use volume = mass ÷ density: 10 g ÷ 2 g/mL = 5 mL.
  3. Check the unit and conclusion: The correct answer is 5 mL.

Use volume = mass ÷ density: 10 g ÷ 2 g/mL = 5 mL.

5. QuestionMultiple choice

Which expression represents heat gained or lost in a temperature change?

Please select an answer first.

Correct answer: A

The correct answer is q = mcΔT.

  1. Identify the matter or energy concept: Determine whether the question asks about a property, state, phase change, heat transfer, energy form, conservation, density, or specific heat.
  2. Use the relationship or observation: The relationship q = mcΔT uses mass, specific heat capacity, and temperature change.
  3. Check the unit and conclusion: The correct answer is q = mcΔT.

The relationship q = mcΔT uses mass, specific heat capacity, and temperature change.

6. QuestionMultiple choice

If the mass and temperature change stay constant, what happens to heat q when specific heat c increases?

Please select an answer first.

Correct answer: B

The correct answer is The heat required increases..

  1. Identify the matter or energy concept: Determine whether the question asks about a property, state, phase change, heat transfer, energy form, conservation, density, or specific heat.
  2. Use the relationship or observation: Because q is proportional to c when other factors are fixed, greater specific heat requires more energy.
  3. Check the unit and conclusion: The correct answer is The heat required increases..

Because q is proportional to c when other factors are fixed, greater specific heat requires more energy.

7. QuestionMultiple choice

How much heat is needed to warm 10 g of water by 5 °C if c = 4.18 J/(g·°C)?
