- Water
- Mercury
- Ink
- Kerosene
Show answer and solution
Correct answer: B. Mercury
Mercury cohesion exceeds its adhesion to glass, so it does not wet glass.

Worked practice questions
Raindrops and soap bubbles take a spherical shape because of which property?
- Viscosity of air
- Mass density
- Surface tension
- Compressibility
Show answer and solution
Correct answer: C. Surface tension
Surface tension minimises surface area, and a sphere has the least area for a given volume.
A water spider walking on still water is possible due to what?
- Water buoyancy
- Air pressure
- Capillary rise
- Surface tension
Show answer and solution
Correct answer: D. Surface tension
The surface film acts like a stretched membrane that supports the light spider.
