Question

The relative density of a substance is the ratio of the density of the substance to the density of water at $40°C$.

• A. True
• B. False

Answer 1

The correct option is B False

1. Relative density is the ratio of the density of a substance to the density of a standard substance under specified conditions.
2. The formula of relative density or $R.D=\frac{densityofsubs\tan ce}{densityofwaterat4°C}$
3. Generally, water is considered as a standard substance and its temperature should be $4°C$ while taking its density.
4. Also, relative density is a dimensionless quantity as it is the ratio of two similar quantities.

Hence, this statement is False.
