Question

why does ink stick to surface of paper?​

Answer 1

Explanation:

Put into very basic terms, ink sticks to paper because it has a high affinity for the medium it's being applied to. ... When ink is drawn onto a surface that it doesn't like, it aggregates, it sort of clumps together, as if it is trying to avoid any interaction with the surface.

Answer 2

Answer:

IF WE SEE A PAPER THROUGH A MAGNIFYING GLASS ,WE WILL SEE THAT PAPER ACTUALLY CONTAINS A LOT OF VOIDS OR HOLES IN ITS SURFACE

THE INK GETS INTO THIS VOIDS OR HOLES AND STICK THERE,

IF WE TAKE THE CASE OF ALUMINIUM PAPER WE ARE UNABLE TO WRITE ON IT BECAUSE ALUMINIUM HAS NO VOIDS AND INK DOESNT STICK THERE.
