Thermal properties written questions
Answer G3 Pure / O-Level heat-capacity and latent-heat questions, checking energy calculations and state changes with marking guidance.
Learning goals
- Describe internal energy as the total kinetic energy of the particles' random motion plus the total potential energy between them
- Apply energy transferred = mass × specific heat capacity × temperature change
- Describe melting, solidification, boiling and condensation as energy transfers without a change in temperature
- Apply energy transferred for a change of state = mass × specific latent heat
- Explain latent heat using particle behaviour
