Question

Select the phrases that correctly describe density. Density is a chemical property. 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).

Answer 1

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)

Step-by-step explanation:

Density
`D` is a characteristic property of a substance or material and is defined as the relationship between the mass
`m` of a body or substance and the volume
`V` it occupies:

`D=(m)/(V)`

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
`D=(kg)/(m^(3))` , although it can be also expressed in
`(g)/(ml)`.

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.
