The surface tension of a liquid, at critical temperature is____________________?
Correct answer: C. Zero
- A. Indeterminate
- B. Infinity
- C. Zero
- D. Same as that at any other temperature
Explanation
At the critical temperature, the liquid and vapour phases become indistinguishable and the liquid-vapour interface disappears. Consequently, surface tension falls to zero.
