Question

Take two a glass /breaker filled with water .put a drop of blue or red ink slowly and carefully along the side of the first beaker and honey in the same way in the second beaker

Answer 1

1 Observe the water and ink in the beaker.Initially, the ink does not mix with water. After some time it starts spreadingslowly. After a few hours, the whole of water in the glass becomes coloured due to diffusion of ink through the water.The above activity demonstrates that diffusion occurs in liquids. Why does ithappen? Because the molecules of both the liquids are moving and help in the diffusion process.
2 The liquids withhigher viscosity flow slowly and are more viscous in nature like glycerol orhoney. Water and alcohol have lower viscosity and are less viscous in nature.
