A gas has a pressure of 200 kPa and a volume of 3.0 m³. The gas is compressed at constant temperature until its volume is 1.5 m³. What is the new pressure?

Q: How do I try a free AQA Physics question?

Just tap any of the four options on this page — no signup, no card, nothing to install. You'll see the correct answer and a full mark-scheme-style explanation within a second. Each visit shows a fresh randomly-picked question from the live AQA GCSE Physics bank, so you can keep refreshing to try different ones before deciding whether to create a free account for daily access.

Q: Is Kramizo really free for AQA Physics students?

Yes — completely free. Every student gets 45 questions a day on the free plan, across any board and any subject, with no card required and no trial countdown. Kramizo's optional Pro plan removes the daily cap and adds analytics, but the free plan is genuinely free forever. We make money from the small percentage of students who choose to upgrade — not from selling data or ads.

Q: Are the Physics questions aligned to the AQA GCSE syllabus?

Every question is written against the published AQA GCSE Physics syllabus and reviewed for accuracy before being added to the bank. We match the command words (state, describe, explain, evaluate), mark allocations, and difficulty tier you'll see on real AQA past papers. Explanations are written in the style of official examiner mark schemes so students learn exactly what marks are being awarded for.

Question

A gas has a pressure of 200 kPa and a volume of 3.0 m³. The gas is compressed at constant temperature until its volume is 1.5 m³. What is the new pressure?

Accepted Answer

C) 400 kPa — Using Boyle's Law: P₁V₁ = P₂V₂, so 200 × 3.0 = P₂ × 1.5, giving P₂ = 600 ÷ 1.5 = 400 kPa. The volume halved, so the pressure doubled. Option A is incorrect as it would imply doubling the volume.

Answer

A) 100 kPa

Answer

B) 300 kPa

Answer

C) 400 kPa

Answer

D) 600 kPa
