Quick revision
Class 9 Chemistry MCQs Matter are one of the fastest ways to improve your board exam performance — especially when you practice with purpose, revise weak concepts, and learn from explanations.
On Prepzy, you can practice 52 MCQs from “Matter” in Chemistry for FBISE. Each question is designed to mirror the style, wording, and concept-testing approach used in Pakistani board papers.
Use this chapter page to revise definitions, formulas, and key ideas, then attempt the MCQs in small sets. Track patterns in your mistakes: is it a concept gap, a calculation error, or a misread statement? Fixing the pattern is what raises your score.
If you’re preparing for matric / SSC Part exams, focus on understanding the concept first, then speed. MCQs reward clarity — not memorization. A clear concept turns into fast correct answers.
What to focus on
- Primary focus: Matter concepts tested in Class 9 Chemistry
- Practice with instant answer-checking to reduce repeated mistakes
- Revise common definitions, units, and standard results before timed practice
- Aim for accuracy first, then build speed with short quizzes
Study tips
- Read the question stem first, then scan options for distractors (near-correct choices).
- If the chapter is formula-heavy, write a mini-formula sheet and revise it before every attempt.
- After each practice set, re-attempt only the wrong MCQs to convert weak areas into strengths.
- Mix easy + medium MCQs for momentum, then finish with hard questions for exam readiness.

- A property of solutions to dissolve
- The scattering of light by particles in a colloid
- A method to separate mixtures
- The property that allows particles to settle
Answer & explanation
Correct: The scattering of light by particles in a colloid
The Tyndall effect refers to the ability of colloidal particles to scatter light, visible in the path of the beam.
