Consider the following statements :
If there were no phenomenon of capillarity
1. It would be difficult 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. The big trees that we see around would not have grown on the Earth
Which of the statements given above are correct?
Explanation:
Capillary action is the ability of a liquid to flow in narrow spaces without the assistance of, or even in opposition to, external forces like gravity.Bloating paper, kerosene lamp and plants perform capillary action for their functioning, while straw works based on external pressure generated.So statements 1, 3 and 4 are correct.
