Answer:
Aim: To observe what happens to the ink drop and the drop of honey after being added and conclude.
Materials Required: Two beakers,water, red ink, honey, two droppers.
Procedure:
(i) Fill the two beakers with water.
(ii) With the first dropper put a drop of red inkslowly and carefully along the sides of the first beaker.
(iii) Now with the second dropper, put a drop of honey slowly and carefully along the sides of the second beaker.
(iv) Now leave the beaker undisturbed and record your observations.
Observations:
- The red ink starts spreading immediately after reaching the water. It spreads uniformly throughout the water in 20 minutes.
The drop of honey first sinks to the bottom and then starts spreading very slowly.
Conclusions:
- Particles of matter are constantly moving because they possess kinetic energy. Due to this the ink spreads rapidly through the water.
- Some particles possess lower kinetic energy that other particles. In this case, particles of honey have lower kinetic energy than particles of ink. Hence, it does not spread rapidly.
