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

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 , although it can be also expressed in .

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.

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.
