Q144 / 200 · Manipal (MET) 2010 · Physics

Surface tension vanishes at

A
absolute zero temperature
B
transition temperature
Correct answer
C
critical temperature
D
None of the above

Solution

The surface tension of liquids decreases with increase of temperature. For small temperature difference it decreases almost linearly. The surface tension of a liquid becomes zero at a particular temperature, called the critical temperature of that liquid.

Hence, the correct answer is option: 'C'.
