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.
