Consider the following statements: If there were no capillarity: 1. It would be impossible to use a kerosene lamp. 2. One would not be able to use a straw to consume a soft drink. 3. The blotting paper would fail to function. 4. There would have been no plants on Earth.
Q1. Consider the following statements: If there were no capillarity: 1. It would be impossible to use a kerosene lamp. 2. One would not be able to use a straw to consume a soft drink. 3. The blotting paper would fail to function. 4. There would have been no plants on Earth.
Answer: 1, 3, and 4 are correct
Explanation: Capillary action is essential for a kerosene lamp wick (1), blotting paper absorption (3), and water transport in plants (4); drinking through a straw uses suction pressure, not capillarity.
