Consider the following statements:If there were no phenomenon of capil...
Explanation:
Capillarity is the phenomenon of the rise or fall of a liquid in a narrow tube against the force of gravity. It occurs due to the cohesive and adhesive properties of the liquid. Capillarity is responsible for various everyday phenomena, and without it, certain activities and natural processes would not be possible. Let's analyze each statement to understand why the correct answer is option 'B'.
1. It would be difficult to use a kerosene lamp:
- In a kerosene lamp, a wick is used to draw up the kerosene oil, which is then burned to produce light.
- Capillarity helps in the upward movement of the oil through the wick, ensuring a steady supply of fuel to the flame.
- Without capillarity, the kerosene oil would not be able to rise up the wick, making it difficult to use the lamp.
2. One would not be able to use a straw to consume a soft drink:
- When we suck on a straw, we create a partial vacuum inside the straw.
- Capillarity allows the liquid to rise up the straw and into our mouth, even against the force of gravity.
- Without capillarity, the liquid would not be able to flow up the straw, making it impossible to consume a drink using a straw.
3. The blotting paper would fail to function:
- Blotting paper is a highly absorbent paper used to soak up excess ink or liquid spills.
- Capillarity allows the liquid to be drawn into the tiny spaces between the paper fibers, facilitating absorption.
- Without capillarity, the liquid would not be able to move into the paper, rendering the blotting paper ineffective.
4. The big trees that we see around would not have grown on the Earth:
- Capillarity plays a crucial role in the transportation of water from the roots to the leaves of a tree.
- Water moves upwards through tiny capillary tubes present in the xylem tissue of the tree, against the force of gravity.
- Without capillarity, water would not be able to reach the upper parts of the tree, hindering its growth and survival.
In conclusion, all the statements are correct. Capillarity is a fundamental phenomenon that is responsible for various everyday activities and natural processes. Without it, using a kerosene lamp, consuming drinks with a straw, functioning of blotting paper, and the growth of big trees would not be possible. Therefore, the correct answer is option 'B' (1, 3, and 4 only).
