Question:
The surface tension of a liquid at its boiling point
The surface tension of a liquid at its boiling point
Show Hint
Surface tension becomes zero at the critical temperature (boiling point) where liquid and gas phases become indistinguishable.
Updated On: Apr 23, 2025
- becomes zero
- becomes infinity
- is equal to the value at room temperature
- is half of the value at room temperature
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
At the boiling point, the liquid converts to vapor and intermolecular forces reduce significantly.
As surface tension is due to cohesive forces, it vanishes at boiling point.
\[
\text{Therefore, } \text{Surface Tension} = 0
\]
