Question 1 · 1 mark · Difficulty 1/3

What causes the pressure exerted by a gas on the walls of its container?

  1. A) Gas molecules pushing each other apart and pressing outward
  2. B) Gas molecules colliding with the container walls and exerting a force
  3. C) Gas molecules sticking to the walls and pulling them inward
  4. D) Gravity pulling gas molecules downward onto the base of the container
Show answer & explanation
✓ Answer: BB) Gas molecules colliding with the container walls and exerting a force
Gas pressure arises from the repeated collisions of gas molecules with the container walls. Each collision exerts a small force, and the total effect of billions of collisions per second produces measurable pressure. Molecules do not stick to walls or push each other to create pressure.
Question 2 · 1 mark · Difficulty 1/3

Which of the following correctly converts a temperature of 127 °C into kelvin?

  1. A) 127 K
  2. B) 400 K
  3. C) 354 K
  4. D) 246 K
Show answer & explanation
✓ Answer: BB) 400 K
To convert Celsius to Kelvin, add 273: 127 + 273 = 400 K. A common misconception is to subtract 273 (giving 246 K, option D) or to leave the value unchanged. Option C results from adding an incorrect value of 227.

AQA GCSE Physics: Particle motion in gases and pressure FAQ

How many AQA GCSE Physics questions on Particle motion in gases and pressure are there on Kramizo?
Kramizo currently has 20 exam-board-aligned practice questions on Particle motion in gases and pressure for AQA GCSE Physics, 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 AQA 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 AQA GCSE students preparing for Physics?
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 Particle motion in gases and pressure practice with other Physics topics or even switch to a totally different AQA 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 Particle motion in gases and pressure questions aligned to the official AQA GCSE Physics syllabus?
Every question is written against the published AQA GCSE Physics specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real AQA 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 AQA.
How is Particle motion in gases and pressure typically tested on AQA GCSE Physics papers?
Particle motion in gases and pressure appears across multiple question types on real AQA GCSE Physics 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.
