The surface tension of a liquid at its boiling point

The surface tension of a liquid at its boiling point
  1. becomes zero
  2. becomes infinity
  3. is equal to the value at room temperature
  4. is half of the value at room temperature

Solution

The interatomic forces decreases or becomes very weak at the boiling point of a liquid. Therefore, surface tension becomes zero.
