Pen ink consists of several ingredients. One of them is a dye which imparts color to the ink. When we add a drop of ink into the cold water, the ink is mixed with it by means of diffusion – dispersion of particles of ink ingredients in the water. The warm water diffusion occurs faster because the particles have more energy, and the spaces between them are larger (more easily with each other squeeze).
