If the temperature of the liquid changes, the S.G. may also change. Because temperature change will cause the liquid to expand or contract, depending on whether the temperature goes below or above the standard temperature.
The S.G. or Mass Density of most liquid is calculated at a Standard...

d=m/v. • Density of a substance is affected by temperature and pressure. These vary according to the physical properties of the substance. The effect of temperature on the density of solids and gases varies widely. Gases are most affected; solids are least and liquids ranging generally in...
