Q. In the figure given below, a glass tumbler is filled with water and the water level is marked with a red marker. In fig -2, marbles are put in the glass tumbler and the water level is noted. Finally, in fig -3, the marbles are removed and the level of water is noted again. These three markings are then compared. It is found that the glass tumbler with marbles has a higher level of water. This experiment proves that matter occupies space.
