Q. What is the reason of surface tension in a liquid?
Solution:
- Surface tension is the property of a liquid by virtue of which, the surface of a liquid acts like a stretched membrane thereby acquiring the least possible surface area.
- This property is attributed to the cohesive forces between the molecules of the liquid. The stronger the cohesive force, the stronger the surface tension.
- Surface tension depends on the nature of the liquid, the surrounding environment and temperature.
