Answer:
Density relates a mass to its volume.
Density varies with temperature
Density determines if a substance floats or sinks.
Density may have units of grams per milliliter (g/mL)
Explanation:
Density [tex]D[/tex] is a characteristic property of a substance or material and is defined as the relationship between the mass [tex]m[/tex] of a body or substance and the volume [tex]V[/tex] it occupies:
[tex]D=\frac{m}{V}[/tex]
This means the density is inversely proportional to the volume.
On the other hand, density is a scalar quantity and according to the International System of Units its unit is [tex]D=\frac{kg}{m^{3}}[/tex] , although it can be also expressed in [tex]\frac{g}{ml}[/tex].
It should be noted that the density of a body is related to its buoyancy, a substance or body will float on another fluid if its density is lower. In addition, if the pressure of the substance remains constant, as the temperature increases, the density decreases; this means density varies with the temperature as well.
