Question 1 · 1 mark · Difficulty 1/3

What happens to particles when a solid is heated to its melting point?

  1. They disappear
  2. They stop moving
  3. They gain enough energy to overcome forces holding them in fixed positions and start moving around each other
  4. They shrink
Show answer & explanation
✓ Answer: C — They gain enough energy to overcome forces holding them in fixed positions and start moving around each other
At the melting point, particles have enough kinetic energy to break from their fixed arrangement. They can now slide over each other (liquid state).
Question 2 · 1 mark · Difficulty 1/3

Bromine vapour is introduced into a gas jar of air. After several minutes, the brown colour of the bromine is evenly distributed throughout both gas jars. Which process explains this observation?

  1. Convection
  2. Diffusion
  3. Condensation
  4. Evaporation
Show answer & explanation
✓ Answer: B — Diffusion
Award 1 mark for identifying diffusion as the net movement of particles from a region of higher concentration to a region of lower concentration. D is incorrect — evaporation is a change of state from liquid to gas. A is incorrect — convection involves bulk movement of fluids due to density differences. C is incorrect — condensation is a change of state from gas to liquid.

CIE IGCSE Chemistry: States of Matter FAQ

Is Kramizo free for CIE IGCSE students preparing for Chemistry?
Yes — completely free. Every student gets 45 questions a day on the free plan, with no card required and no trial countdown. That free quota works across every subject and every topic in our bank, so you can mix States of Matter practice with other Chemistry topics or even switch to a totally different CIE subject without paying anything. Kramizo's optional Pro plan removes the daily cap and adds detailed progress analytics, but the free tier is the real product — used by thousands of GCSE, IGCSE and CSEC students.
Are the States of Matter questions aligned to the official CIE IGCSE Chemistry syllabus?
Every question is written against the published CIE IGCSE Chemistry specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real CIE paper. Explanations are written in the style of official examiner mark schemes — they tell you what is being awarded marks and why distractors are wrong, not just whether you got it right. The bank is continually refined to match the latest syllabus updates from CIE.
How is States of Matter typically tested on CIE IGCSE Chemistry papers?
States of Matter appears across multiple question types on real CIE IGCSE Chemistry papers — most commonly as multiple-choice questions in the objective section, structured short-answer questions in the main paper, and occasionally as part of an extended response. Kramizo's practice bank reflects that mix: 4-option MCQs, true/false statements, fill-in-the-blank key terms, multi-select questions, and ordering questions. Working through the bank gives you exposure to every question style examiners actually use.
