Question 12
Structure of Matter and Kinetic TheoryIf a beaker is filled with water it is observed that the surface of the water is not horizontal at the glass-water interface. This behaviour is due to
- A.friction
- B.viscosity
- C.surface tension
- D.evaporation
Show the answer and explanation
Answer: C (surface tension)
Explanation
Water creeps up the glass to form a curved meniscus because of surface tension and adhesion between water and glass.
