Iron has a melting point of 1538°C and a boiling point of 2862°C. At 2000°C, which statement correctly describes the state and particle arrangement of iron?

Q: How do I try a free CIE Chemistry 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 CIE IGCSE Chemistry 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 CIE Chemistry 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 Chemistry questions aligned to the CIE IGCSE syllabus?

Every question is written against the published CIE IGCSE Chemistry 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 CIE past papers. Explanations are written in the style of official examiner mark schemes so students learn exactly what marks are being awarded for.

Question

Iron has a melting point of 1538°C and a boiling point of 2862°C. At 2000°C, which statement correctly describes the state and particle arrangement of iron?

Accepted Answer

Iron is a liquid with particles close together but able to move past each other — Award 1 mark for recognising that 2000°C is above the melting point (1538°C) but below the boiling point (2862°C), so iron is liquid. In liquids, particles are close together but can move past each other. A is incorrect — this describes a solid below 1538°C. C is incorrect — this describes a gas above 2862°C. D is incorrect — at 2000°C iron is entirely liquid, not at its boiling point.

Answer

Iron is a liquid with particles close together but able to move past each other

Answer

Iron is a mixture of liquid and gas with some particles escaping

Answer

Iron is a solid with particles vibrating in fixed positions

Answer

Iron is a gas with particles far apart and moving randomly
