MCQ
The spherical shape of rain-drop is due to
- ADensity of the liquid
- ✓Surface tension
- CAtmospheric pressure
- DGravity
✓
Answer
Correct option: B.
Surface tension
b
(b) Because of surface tension, a liquid surface tends to have the minimum area possible. And as for a given volume the surface of a sphere has got the minimum area, the rain drops take a spherical shape.
