Spherical shape of mercury droplets is due to its____________________?
Correct answer: D. High surface tension
- A. High viscosity
- B. Low surface tension
- C. High density
- D. High surface tension
Explanation
Mercury has high surface tension, so cohesive forces pull its surface into the shape with minimum area, producing nearly spherical droplets. Its high density affects weight but does not cause the spherical shape.
