3 dot points across 3 inquiry questions. Click any dot point for a focused answer with worked past exam questions where available.

Why do some things heat up faster than others, and why does temperature stay constant while ice melts?

Use specific heat capacity, and explain melting and boiling using latent heat
Use the specific heat capacity formula, describe melting, boiling, freezing and condensing, and explain why temperature stays constant during a change of state at N(A)-Level.

What does temperature really measure, and how does a thermometer work?

Explain temperature and thermal energy flow, and describe how a liquid-in-glass thermometer works
Explain what temperature measures, how thermal energy flows from hot to cold, the Celsius scale and its fixed points, and how a liquid-in-glass thermometer works at N(A)-Level.

How does thermal energy travel by conduction, convection and radiation?

Describe conduction, convection and radiation, and explain everyday ways to control heat transfer
Describe conduction, convection and radiation, identify which works in solids, liquids, gases and a vacuum, and explain how a vacuum flask reduces heat transfer at N(A)-Level.
