Why is it necessary to state the temperature with a density value?

Answer 1

It is necessary to indicate the temperature when giving the density of liquids because temperature effects the density of many liquids. For example, water increases in density as it becomes colder.

Answer 2

Because density is mass divided by volume. D = M/V

The volume of an object changes in different temperature, so therefor it's density changes with it's volume. Volume is size, and size is dependant on temperature.

Answer 3

Density and volume are temperature dependent variables. For example, under normal conditions in which the external pressure of a body is held constant and the body's volume is not constricted, as its temperature increases, so will its volume, while its density will decrease. this is due, generally speaking, to the added kinetic energy gained by the atoms, ions, and/ or molecules that make up the body in question.

Answer 4

that is because density varies with temperature. Most objects expand as temperature increases, thereby increasing in volume. Because density is mass divided by volume, density usually decreases with increasing temperature

Answer 5

It is necessary to indicate the temperature when given the density of a liquid because it changes. Some liquids are different densities at different temperatures.
