Question 8 of 15beginnerShort Answer1 mark

Take a piece of paper and put a drop of water on it. Observe.

Correct Answer

When a drop of water is placed on plain paper, the water spreads and is absorbed by the paper. The paper becomes wet and may become slightly transparent at the spot where the water was placed.

Activity 9 demonstrates the water-absorbing property of plain paper compared to wax-coated surfaces. This helps students understand why aquatic plants have waxy coatings on their leaves.
