Question 1 · 1 mark · Difficulty 1/3

Which statement correctly describes the arrangement and movement of particles in a gas?

  1. Particles are close together and vibrate about fixed positions
  2. Particles are far apart and move randomly at high speeds
  3. Particles are close together and slide over each other
  4. Particles are far apart and vibrate about fixed positions
Show answer & explanation
✓ Answer: BParticles are far apart and move randomly at high speeds
Award 1 mark for identifying that gas particles are far apart and move randomly at high speeds. A is incorrect — this describes the arrangement in a solid. C is incorrect — this describes the arrangement in a liquid. D is incorrect — particles in a gas do not vibrate about fixed positions; they move freely and randomly.
Question 2 · 1 mark · Difficulty 1/3

A student heats a beaker of water from 25°C to 100°C. Which row correctly describes the changes to the water particles during heating?

  1. Particles move faster and move further apart
  2. Particles move slower and move closer together
  3. Particles increase in size and move faster
  4. Particles decrease in size and move further apart
Show answer & explanation
✓ Answer: AParticles move faster and move further apart
Award 1 mark for recognising that heating increases kinetic energy, causing particles to move faster and further apart. B is incorrect — heating increases particle speed, not decreases it. C is incorrect — particles do not change size when heated; only their movement and spacing change. D is incorrect — particles do not decrease in size.

CIE IGCSE Chemistry: The particulate nature of matter FAQ

How many CIE IGCSE Chemistry questions on The particulate nature of matter are there on Kramizo?
Kramizo currently has 20 exam-board-aligned practice questions on The particulate nature of matter for CIE IGCSE Chemistry, with new questions added every week. Each question gives you instant feedback and a full examiner-style mark scheme that tells you exactly what would earn marks on a real CIE paper. The questions span the full difficulty range — from straightforward recall (level 1) right up to multi-step reasoning and evaluation (level 3) — so the bank works for first-pass revision and final exam-week stress testing alike.
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 The particulate nature 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 The particulate nature 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 The particulate nature of matter typically tested on CIE IGCSE Chemistry papers?
The particulate nature 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.
