Question

If 100 cc of water is at 20 degree Celsius, at what temperature its density will be maximum?

Answer 1

Answer:

The density of water is a maximum at 4 °C .

Explanation:

As the temperature of warm water decreases, the water molecules slow down and the density increases. At 4 °C, the clusters start forming. The molecules are still slowing down and coming closer together, but the formation of clusters makes the molecules move further apart. This behavior exhibited by water is known anomalous expansion of water. Thus, density of water is a maximum at 4 °C .
