|
capillary action phenomenon
|
|
|
viscosity of ink

Explanation:
Detailed explanation-1: -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.
Detailed explanation-2: -So, the correct answer is ‘Capillary action’.
Detailed explanation-3: -1 Answer. Blotting paper has fine pores which act as capillaries. The ink rises in these capillaries. Thus, the ink is absorbed by the blotting paper.
