Name the device used to check the relative density of sulphuric acid in an acid battery.

The ratio of density of a substance to the density of water at $4°\mathrm{C}$ is known as the _____ of the substance.

A hollow metal of mass $180.6 \mathrm{g}$ contains a cavity of volume $2.5 {\mathrm{cm}}^3$. The metal when placed in water displaces $24 \mathrm{cc}$ of water. The specific gravity of metal is: 

Hydrometer is an instrument used for direct determination of relative density of a liquid.

What is the relative density of $10 \mathrm{kg}$ of water occupied in $5 {\mathrm{m}}^3$ with respect to $100 \mathrm{g}/{\mathrm{m}}^3$?

It is necessary to mention the temperature at which specific gravity is calculated because

The relative density of any substance is equal to the ratio of the mass of any volume of the substance to the mass of an equal volume of water.

_____ hydrometer is used to check the relative density of sulphuric acid in an acid battery.
