Question

Why is relative density calculated with respect to the density of water particularly at $4^{\circ }C$?

• A. Because water displays Archimedes principle at $4^{\circ }C$
• B. Water has the highest density at $4^{\circ }C$
• C. Water starts turning into ice at $4^{\circ }C$
• D. All of the above

Answer 1

The correct option is B Water has the highest density at $4^{\circ }C$

Relative density is defined as the ratio of the density of any substance to the density of water at $4^{\circ }C$. The density of water is maximum at $4^{\circ }C$ and is regarded as a standard to calculate the relative density of any substance.
