Question

when water contracts from 4°c to 0°c, density of water​

Answer 1

Answer:

The density of water decreases when you cool it from 4° to 0°C

Explanation:

When liquid water is cooled, it contracts until a temperature of approximately 4°C is reached. After that, it expands slightly until it reaches the freezing point.The distance between the H−O bond is more than the O−O bond 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.

The density of water is maximum at 4°C
