Question

prepare various solutions whit different densities by adding some drops of ink in different amounts of water and explain the principle involved in it the your friends​

Answer 1

Answer:

Explanation:

Ink diffuses in water because of the random motion of ink molecules in water.

Some of the basic principles behind the mixture of ink and water are the collision of molecules, then diffusion and finally the random movement of molecules  

When drops of ink are dropped into water, the water molecules make haphazard movement and collide with the ink molecules. Now, the ink molecules also make haphazard movement and move from area of higher to lower concentration of molecules.
