Question

Surface tension does not vary with temperature.
If true 1 else 0.

• A. 0

Answer 1

The correct option is A 0
It is a property by virtue of which, the free surface of a liquid possesses a tendency to contract so as to acquire a minimum surface area.
Factors affecting Surface Tension
The presence of impurities either on the surface or dissolved in it, affect surface tension of the liquid. Highly soluble substances increase the surface tension of water, whereas sparingly soluble substances reduce the surface tension of water.
The surface tension of a liquid decreases with increase in temperature. The surface tension of a liquid becomes zero at its boiling point and vanishes at critical temperature.
