A piece of ice is floating in a beaker containing water up to its brim. When the whole of the ice melts
- Athe water will spill on the floor
- Bthe level of water will come down in the beaker
- Cthe level of water will first fall and then it will spill out of the beaker
- Dthe water level will not change
- ENone of the above/More than one of the above
Show answer and explanation
Correct answer: (d) the water level will not change
Explanation
Floating ice displaces a volume of water whose weight equals the weight of the ice (Archimedes' principle).
On melting, the ice turns into water of exactly the same volume it had displaced.
The displaced volume is precisely replaced, so the water level does not change.
