The maximum density of water occurs at a temperature of?

A. 0°C
B. 4°C
C. 37°C
D. 273°C

Correct Answer: Option B

B. 4°C

Explanation

This is as a result of the Hydrogen bonding in water. Due to the high Kinetic Energy of water, the hydrogen bonds can’t hold for too long but from 4°C, there’s an increase in the hydrogen bonds hence strengthening it. From the point of production of more hydrogen bonds, the bonding is no longer easily broken. Generally, these and a few factors based on these cause the density of water to be maximum at 4°C.
