The absorption of ink by blotting paper involves__________?
Correct answer: B. Capillary action phenomenon
- A. Viscosity of ink
- B. Capillary action phenomenon
- C. Diffusion of ink through the blotting
- D. Siphon action
Explanation
Blotting paper contains very fine pores, and adhesion plus capillary action draws the ink into these narrow spaces. Siphon action requires a connected liquid column and is not involved here.
