density changes when the substance changes.


What is the density of banded sandstone?

The density of sandstone ranges quite considerably, usually between 2.0 and 2.6 Kg/m3 (more usually 2.23 to 2.5).


What is the relationship between the density of a substance and its specific gravity?

The specific gravity of a substance is the ratio of its density to the density of a reference substance (usually water). Specific gravity is a dimensionless quantity that allows us to compare the density of different substances without units.

The unit for density is kg m-3.


How can you use density to see if an object can float?

Usually, an object can float if it has a lower density than the liquid it is in.


How is density different from relative density?

Density is a measure of how much mass is contained in a given volume of a substance, while relative density is the ratio of the density of a substance to the density of a standard substance (usually water). Relative density is a dimensionless quantity used for comparison purposes.


How does density change?

Density usually changes when an object is heated or cooled - especially in the case of gases, or when there is a change of phase.


How do you determine the density of matter?

Usually you would use the basic definition of "density": just divide mass by volume.


How does temperature usually affect density?

Density is usually expressed in some unit of mass, divided by some unit of volume. As a result, the SI unit, of course, is kilogram / cubic meter. In this case, water would have a density of about 1000. In practice, it is often expressed in kilogram per liter, or the equivalent, gram per cubic centimeter, in which case water has a density of approximately 1.
