The surface tension of a liquid at its boiling point
- A becomes zero
- B becomes infinity
- C is equal to the value at room temperature
- D is half of the value at room temperature
Answer & Solution
Correct Answer
(A) becomes zero
Step-by-step Solution
Detailed explanation
Surface tension is a property of liquids that arises due to the cohesive forces between molecules at the surface. As the temperature of a liquid increases, the kinetic energy of the molecules increases, which weakens the intermolecular forces of attraction. At the boiling point,…
