Question

Falling drops of water becomes sphere due to the

• A. Surface tension
• B. cohesion
• C. adhesion
• D. Viscosity

Answer 1

Answer:

A. Surface tension

Surface tension is the property of a liquid that causes its free surface to behave like an elastic stretched membrane. A small liquid drop takes a spherical shape due to the minimum surface area for a given volume, caused by surface tension. Applications of surface tension include capillary action, which draws ink to the tips of fountain pen nibs, and the warm soup tastes tasty as its surface tension is low at high temperatures
