  In the above question, what will happen if instead of water the glass is filled with (a) a liquid denser than water. (b) a liquid lighter than water.

Answer:

                  (a) When the liquid denser than water is filled in the glass, then the volume of water formed by the melting of ice will be more than the volume of the liquid displaced, so the level of water will rise. Therefore, the water will overflow from the glass. (b) When the liquid lighter than water is filled in the glass, the level of water in the glass will come down. So, the water will not overflow from the glass.
