Year 9
Thermal
Use the kinetic theory model to explain states of matter, thermal expansion, heating, specific heat capacity, and latent heat.
Part of Year 9 Physics Foundations.
Topic Overview
What students will cover
This topic introduces particle thinking as a model for thermal behaviour. Students should move between observation and explanation, using the particle model to account for heating, cooling, and changes of state.
Practical planning and careful interpretation remain important here, especially where temperature data and cooling curves are involved.
