A gas has an initial pressure of 200 kPa and volume of 3.0 m³ at constant temperature. The volume is reduced to 1.5 m³. What is the new pressure?

Q: How do I try a free Edexcel 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 Edexcel 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 Edexcel 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 Edexcel GCSE syllabus?

Every question is written against the published Edexcel 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 Edexcel 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 an initial pressure of 200 kPa and volume of 3.0 m³ at constant temperature. The volume is reduced to 1.5 m³. What is the new pressure?

Accepted Answer

400 kPa — Using Boyle's Law: P₁V₁ = P₂V₂. So P₂ = (200 × 3.0) / 1.5 = 600 / 1.5 = 400 kPa. Option A is wrong — halving the volume doubles, not halves, the pressure. Option B adds the pressures incorrectly. Option D would be correct only if volume decreased to 1.0 m³.

Answer

600 kPa

Answer

300 kPa

Answer

400 kPa

Answer

100 kPa
