Question

Why do we consider density of water at 4°C only while defining the term 'relative density'?¿

Answer 1

Explanation:

Relative density is defined as the ration of density of any substance to the density of water at 4∘C. The density of water is maximum at 4∘C i.e. equal to 1 and is regarded as a standard to calculate the relative density of any substance.

Answer 2

Answer:

We calculate relative density with respect to water. Why? Generally, the density of water at 4 °C (the temperature at which the density of water reaches its maximum value) is used as the reference to measure relative density.
