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:
Option D – the level of water drops
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 volume 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.
