Questions with solutions
Q1 — Magnetic Separation & Distillation · easy · theory
A magnet can be used to separate …
A. Iron pieces from a mixture ✓ Correct
B. Sugar from tea
C. Salt dissolved in water
D. Two gases
Solution: A magnet attracts iron, so it can pull iron pieces out of a mixture. This is magnetic separation.
Q2 — Magnetic Separation & Distillation · easy · theory
Which of these will a magnet attract?
A. A glass marble
B. An iron nail ✓ Correct
C. A wooden block
D. A plastic spoon
Solution: Iron is a magnetic material, so a magnet attracts the iron nail but not plastic, glass or wood.
Q3 — Magnetic Separation & Distillation · easy · theory
Magnetic separation is a good way to separate iron filings from …
A. A heap of sand ✓ Correct
B. Boiling water
C. Salt water
D. Two mixed gases
Solution: A magnet picks up the iron filings while the sand is left behind, cleanly separating the two.
Q4 — Magnetic Separation & Distillation · easy · theory
Which of these materials is NOT attracted by a magnet?
A. Steel
B. Nickel
C. Iron
D. Plastic ✓ Correct
Solution: Iron, steel and nickel are magnetic, but plastic is not attracted by a magnet.
Q5 — Magnetic Separation & Distillation · medium · theory
Distillation is used to get back pure water from salt water because it …
A. Collects the pure water AND leaves the salt behind ✓ Correct
B. Only leaves the salt behind and throws away the water
C. Uses a magnet
D. Uses a sieve
Solution: In distillation the water is boiled to vapour and then cooled back to liquid, so we collect pure water while the salt stays behind.
Q6 — Magnetic Separation & Distillation · medium · theory
In distillation, the water vapour is cooled and turns back into liquid water. This change is called …
A. Sedimentation
B. Filtration
C. Evaporation
D. Condensation ✓ Correct
Solution: When vapour is cooled and turns back into liquid, the change is called condensation.
Q7 — Magnetic Separation & Distillation · medium · numerical
A magnet is used on a 50 g mixture of sand and iron filings, and it pulls out 12 g of iron filings. How much sand is left?
A. 12 g
B. 38 g ✓ Correct
C. 50 g
D. 62 g
Solution: Sand left = total mixture − iron removed = 50 − 12 = 38 g.
Q8 — Magnetic Separation & Distillation · medium · theory
How is distillation different from plain evaporation?
A. Evaporation collects the water back
B. They are exactly the same
C. Distillation uses a magnet
D. Distillation collects the water back, while evaporation lets the water escape ✓ Correct
Solution: Evaporation loses the water to the air, but distillation cools the vapour and collects the pure water back as well.
Q9 — Magnetic Separation & Distillation · hard · theory
To get pure drinking water from salty sea water, the best method is …
A. Winnowing
B. Simple evaporation
C. Distillation ✓ Correct
D. Magnetic separation
Solution: Distillation removes the salt AND gives back clean liquid water, so it is the best way to get pure water from sea water.
Q10 — Magnetic Separation & Distillation · hard · theory
A magnet cannot separate a mixture of sand and sugar because …
A. Sand and sugar are both too heavy
B. Neither sand nor sugar is attracted by a magnet ✓ Correct
C. The magnet is too small
D. Sugar dissolves in the magnet
Solution: A magnet only attracts magnetic materials like iron; since neither sand nor sugar is magnetic, a magnet cannot separate them.
