The absorption of ink by blotting paper involves: A. Viscosity of ink B. Capillary action phenomenon C. Diffusion of ink through the blotting D. Siphon action
The correct answer is Capillary action phenomenon. The absorption of ink by the blotting paper is based on the capillary action phenomenon because the blotting paper is a thin and smooth paper that allows a little thicker liquid like ink to absorb on its surface
