Question 1 · 1 mark · Difficulty 1/3

During the distillation of rum at a distillery in Jamaica, the mixture is heated. Which statement correctly describes why the alcohol evaporates before the water?

  1. Alcohol has a higher density than water
  2. Alcohol has a lower boiling point than water
  3. Alcohol molecules are larger than water molecules
  4. Alcohol conducts heat better than water
Show answer & explanation
✓ Answer: BAlcohol has a lower boiling point than water
Award 1 mark for identifying that alcohol boils at approximately 78°C while water boils at 100°C. A is incorrect — alcohol has lower density than water. C is incorrect — molecular size is not the determining factor for boiling point. D is incorrect — thermal conductivity does not determine boiling point.
Question 2 · 1 mark · Difficulty 1/3

A student in Trinidad investigates evaporation by placing equal volumes of water in four identical containers. She places one in the sun, one in the shade, one with a fan blowing, and one covered with a lid. Which container would show the LEAST amount of evaporation after one hour?

  1. Container in the sun
  2. Container in the shade
  3. Container with a fan blowing
  4. Container covered with a lid
Show answer & explanation
✓ Answer: DContainer covered with a lid
Award 1 mark for identifying that the covered container limits evaporation because the air above the water quickly becomes saturated with water vapour, preventing further net evaporation. A, B, and C all allow water vapour to escape into the open air.

CXC CSEC Physics: Evaporation and Boiling FAQ

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