Which property means water does not pass through easily?
A
transparent
B
brittle
C
waterproof
D
soluble
Explanation
Waterproof materials resist water penetration.
Which material is best for a raincoat?
A
sponge
B
salt

Which property is most important for electrical wires?
A
electrical conductivity
B
sweet taste
C
absorbency

B
Guess by colour
C
Use equal-sized samples and the same water volume
D
Use only one material
Explanation
Controlled variables make a fair comparison.
Which test compares hardness?
A
Measure shadow length
B
Listen for loudness
C
Dissolve them all
D
Try scratching materials with the same object
Explanation
Scratch resistance indicates hardness.
Which summary is correct?
