Single correct option
A block of ice floats in a beaker filled to the brim with water. When the ice melts completely, the water level will
- A. fall below the brim
- B. rise and overflow
- C. first rise and then fall
- D. remain unchanged without overflow
Show answer and solution
Answer: (D) remain unchanged without overflow
The floating ice displaces water whose weight equals the ice's weight. After melting, the ice turns into exactly this mass of water, which has the same volume as the displaced water, so it just fills the space. The level stays the same and nothing spills.
