If a container is filled with ice to the brim, what happens to the level of water when the ice completely melts?
A
the level of water goes up
B
the water in the glass outflows
C
the level of water remains unchanged
D
the level of water drops
Verified Correct Answer: D.
Physical Principles & Numerical Solution
The container is filled 'only with ice' to the brim (no liquid water mentioned).
Ice is less dense than water (it expands when freezing).
When the ice melts, the same mass turns into water that occupies less volume.
Result: The water level drops below the brim.
