Question

an ice cube floats on the surface of water filled in a glass tumbler density of ice is 0.9 grams per centimetre cube will the water level rise in the glass when ice melts completely

Answer 1

There will be no rise in the level of water

Answer 2

• By the Archimedes' principle When an ice block is floating on water, the amount of water displaced by the ice is equal to the mass of the ice.

• As we know that mass of ice is conserved, Ice and water both have same mass but have different volume.

• Thus when ice melts, the level of water will remain unchanged.
