Question

What involves in absorption of ink by a tissue paper

Answer 1

A. viscosity of ink

B. capillary action phenomenon

C. diffusion of ink through the blotting

D. siphon action

Answer 2

ANSWER:

The ink absorption by tissue paper involves 'capillary action'.

EXPLANATION:

Capillary action is the capability of liquids to flow in narrow spaces in opposition to the external forces of gravity. The capillary action takes place because the adhesive forces are more stronger to the cohesive forces.

Absorption of ink by tissue paper takes place because the 'inter-molecular forces' between the liquid and solid are more stronger than the 'cohesive forces' between the molecules of the liquid.
