On burning of an incense stick or agarbatti, the fragrance spreads to every part of the room. It means, with increase in temperature the kinetic energy of the particles increases. As the temperature rises, particles move faster. The random, zig-zag movement of the small particles suspended in a liquid or a gas is called Brownian motion. Any particle in motion, possesses kinetic energy. ![]() Particles of matter continuously move in all directions. Particles of matter are continuously moving – Similarly, particles of sugar, salt, or dettol get evenly distributed in water.Ģ. Thus, it is concluded that there must be millions of tiny particles in a very small crystal of potassium permanganate or in a small drop of blue ink, which keeps on dividing themselves into smaller and smaller particles as these purple coloured potassium permanganate particles spread throughout the water and make it purple. If we keep on diluting the potassium permanganate solution like this a number of times (5-7 times), we find that the colour of water is still coloured but becomes lighter and lighter. The colour of solution will become a bit lighter. (ii) Now, we take 10ml of deep purple solution of potassium permanganate in an another beaker and mix it with 90ml of water.
