IAS General Studies Prelims Question No. 65
A container is filled with water at 4°C. The water will overflow if the temperature of water is __:
[C] Increased or decreased
[D] None of them
The reason is the anomalous expansion of water. The maximum density of water occurs at 4°C. So the water expands whether it is heated above 4°C or cooled below 4°C.
