Solution

The correct option is A When cooled below 4 degrees Celsius, it starts expanding until it becomes ice at 0 degrees Celsius
The anomalous expansion of water is the property of water where by it expands instead of contracting when temperature goes from $4^{o} C$ to $0^{o} C$

The temperature recorded at 12 noon was 15 degrees celsius above 0. it decreases at the rate of 3 degree Celsius per hour until midnight ,at what time would the temperature be 9 degree Celsius below zero. What t would be the temperature at midnight?

Q. Assertion :When liquid water is cooled, it contracts until a temperature of approximately 4 degrees Celsius is reached. After that, it expands slightly until it reaches the freezing point. Reason: The distance between the H-O bond is more than the O-O attraction in the water. Hence, the water freezing over into ice is held together not by the O-O attraction but by the H-O attraction.
