Question

why is surface tension temperature dependent????​

Answer 1

Answer:

Becuase cohesive force decreases with increase in thermal activity/ temperature which decreases surface tension

Answer 2

Answer:

Surface Tension and Temperature

As the temperature of a liquid increases, its surface tension decreases. When water heats up, the movement of its molecules disrupts the imbalanced forces on the surface of the water and weakens its sheet-like barrier of tightly bound molecules, thereby lowering the surface tension.
