Question

At critical temperature, the surface tension of a liquid

Answer 1

Explanation:

The rule of thumb is that surface tension decreases with the increase of temperature, reaching a value of zero at the critical temperature. ... The density, molar mass and the critical temperature of the liquid have to be known. At the critical point the surface tension is always zero.
