States of matter: one question to try now
Real past-paper questions, the answer key from the mark scheme, and the explanation that goes with it. No account needed to answer them.
Question 1
Which change is represented by the diagram?
Answer: B.
What this practice covers
These questions are drawn from past CIE 0654 Co-ordinated Sciences papers and filtered to states of matter. 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 states of matter, taken from our own topic notes. Read them before you practise and you will recognise the traps in the questions.
- Saying the particles in a liquid are arranged regularly.
- Saying the particles in a liquid are much further apart than in a solid. They are only slightly further apart.
- Saying compressing a gas makes its particles move faster.
- Saying heating a gas makes its particles bigger, or that they expand. The particles are unchanged; only their spacing and speed alter.
- Explaining a rise in gas pressure by more frequent collisions only, without saying the collisions are also harder.
- Treating evaporation and boiling as the same process.
- Saying evaporation only happens at the boiling point.
- Saying heavier gases diffuse faster because they have more momentum.
