Give a simple experiment to show that matter occupies space.
✓
Answer
Aim : To show that matter occupies space
Materials Required : A glass tumbler, water, a stone, a piece of thread, a glass bowl Procedure:
1. Take a glass tumbler and place it in a bowl. Pour water gently in the tumbler so that it is completely filled.
2. Now take a small stone. Tie it with a piece of thread and lower this stone gently into the tumbler. What do you observe?
3. Remove the stone from the glass tumbler. See the level of the water in the tumbler. Now pour the water collected in the bowl into the tumbler. What do you observe ?Observations :
1. When the stone is lowered into the glass tumbler filled completely with water, some water overflows from the glass tumbler and collects in the bowl (figure b).
2. When the stone is removed from the glass tumbler and the water collected in the bowl is poured back into the tumbler, the water fills have glass tumbler up to the brim again (figure d).Conclusion : From the above observations, we conclude that matter occupies space. The stone occupies space and hence pushes the water out of the tumbler. Water is matter too and also occupies space. This is observed when it fills the tumbler up to its brim.
