If a container is filled with ice to the brim, what happens to the level of water when the ice completely melts?
- the level of water goes up
- the water in the glass outflows
- the level of water remains unchanged
-
the level of water drops
The correct answer is: D
Explanation
Due to anomalous expansion of water at temperature range (0 - 4)°c, when a given mass of water turns into ice, its volume will increase, while the mass remains constant. Thus, when a given volum of ice melts, the volume of water formed will be less than the volume of ice. Hence, the level of water in the container will drop.
