उत्तर
When a stone is dipped in a glass of water, the water level rises because the stone is a bigger object that cannot be dissolved and adjusted between the water's intermolecular gaps. However, when a spoonful of sugar is added and stirred, the water level does not rise because the sugar particles are smaller and move between the intermolecular spaces in water molecules.
