प्रश्न
Take some water in a glass. Put a lemon in it. Now keep putting salt in the water, half-a-spoon at a time. Were you able to float your lemon in water?
उत्तर
Yes, the lemon would float in water containing excess salt. This is due to the fact that water gets heavier when salt has been added in excess amount. And lemon (lighter in weight) will be able to float on heavier water.
