What causes the free surface of a liquid to have minimum area?
- A Viscosity
- B Surface tension
- C Diffusion
- D Pressure
Answer & Solution
Correct Answer
(B) Surface tension
Step-by-step Solution
Detailed explanation
The cohesive forces between liquid molecules are responsible for the phenomenon known as surface tension. The molecules at the surface of a glass of water do not have other water molecules on all sides of them and consequently they cohere more strongly to those directly…
