When the temperature is increased, surface tension of water:

Aincreases
Bdecreases
Correct Answer
Cremains constant
Dshows irregular behaviour

Solution

SURFACE TENSION:
Surface Tension is a property of liquid at rest by virtue of which a liquid surface gets contracted to aminimum area and behaves like a stretched membrane.
An increase in temperature of water (or any liquid) leads to an increase in kinetic energy of molecules. Thus, intermolecular forces among molecules are lowered and a decrease in surface tension is noticed.
