G3 Pure Physics / O‑Level Physics: Thermal Properties of Matter structured questions
Structured and data-based Paper 2 practice for thermal physics: kinetic model, heat transfer (conduction/convection/radiation), thermal equilibrium, specific heat capacity, and latent heat.
Learning objectives
- describe internal energy as an energy store that is made up of the total kinetic energy associated with the random motion of the particles and the total potential energy between the particles in the system
- Define heat capacity and specific heat capacity
- Apply energy transferred = mass × specific heat capacity × temperature change
- describe melting/solidification and boiling/condensation as processes of energy transfer without a change in temperature
- Explain the difference between boiling and evaporation
- Define latent heat and specific latent heat
- Apply energy transferred for a change of state = mass × specific latent heat
- Explain latent heat using particle behaviour
- Sketch and interpret a cooling curve
