Question

Give reason:

A red ink drop added to a small amount of water in a glass turns the water red in some time.

Answer 1

• The intermixing of one kind of particle with another kind is known as diffusion.
• When we add a drop of red ink to water, the ink particles break down into small tiny particles.
• These tiny ink particles diffuse continuously till all gaps or free space present in water are occupied.
• There is intermixing of red ink and water and this process is known as diffusion.
• Thus, due to diffusion whole container turns into red color.
