describe an experiment to show that matter is composed of particles
Answers
Take 50 mL water in a beaker. Mark the level of water in the beaker. Now, add some salt to the beaker and stir well with the help of a spoon. Observe the level of water now. Add some more salt and repeat the above procedure.
It will be observed that salt disappears after being added to water. However, there is no change in the level of water in the beaker.
This observation can be explained if we assume that matter is made up of particles. A chunk of salt consists of numerous salt crystals. Each crystal of salt is made up of many small salt particles. These particles become dissociated from each other and spread uniformly between the particles of water. Thus, the level of water in the beaker remains the same. These particles are so small that we cannot see them with the naked eye. Hence, it can be concluded that matter is made up of particles i.e. matter is particulate in nature.
Answer:
Take a glass half filled with water. Add some salt to it and stir with a spoon it will be observed that salt disappears. This shows that both salt and water are made up of lots of particles and particles of salt have spread throughout the particles of water. The size of particles is very small that there are invisible to eye. Since both salt and water are matter, hence matter is composed of tiny particles.
