Relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. ... A substance with a relative density greater than 1 will sink. Temperature and pressure must be specified for both the sample and the reference.

Is temperature important in density?

Density is a physical property of substances that compares the relationship between volume and mass. Density is affected by temperature because as temperature increases so does the kinetic energy of the particles.

Why is the temperature at which density is measured specified?

which SI unit would be most appropriate for measuring the mass of a table? ... why is the temperature at which density is measured usually specified? density varies with temperature because volume varies with temperature and density is equal to mass/volume. what solids will float in water?
