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
Correct Answer: 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.
