What this practice covers
These questions are drawn from past CIE 0625 Physics papers and filtered to thermal properties and temperature. You answer, you find out immediately whether you were right, and you get the reasoning for the correct option and for each distractor. Wrong answers go to a mistakes locker so you can come back to exactly those.
Practice is free. You need an account only so your progress and your mistakes are still there next time.

What examiners see students get wrong here
These are the errors that cost marks on thermal properties and temperature, taken from our own topic notes. Read them before you practise and you will recognise the traps in the questions.
- Saying the particles themselves expand when a substance is heated.
- Using the final temperature instead of the temperature change in E = mcΔθ.
- Leaving a mass in grams when c is in J/(kg °C).
- Saying the temperature rises during melting or boiling.
- Saying a narrower capillary tube increases the range; it increases sensitivity and reduces range.
- Saying a bimetallic strip bends towards the metal that expands more.
- Forgetting that water contracts between 0 °C and 4 °C.
Revise it first
If any of the above is unfamiliar, work through the notes before practising: Thermal properties and temperature revision notes.
