Consider the following statements - If there were no phenomenon of capillarity
- It would be difficult to use a kerosene lamp
- One would not be able to use a straw to consume a soft drink
- The blotting paper would fail to function
- The big trees that we see around would not have grown on the earth
Detailed Explanation:
✅ Statement 1 – Correct: Kerosene lamps rely on capillary action to draw kerosene up the wick from the reservoir for combustion.
❌ Statement 2 – Incorrect: Drinking through a straw works by air pressure difference, not capillarity; sucking removes air, allowing atmospheric pressure to push liquid up.
✅ Statement 3 – Correct: Blotting paper absorbs ink/liquid through capillary action in its porous structure and fine fibres.
✅ Statement 4 – Correct: Tall trees depend on capillary action to transport water from roots to leaves against gravity through xylem vessels.
