Final answer:

The relationship between temperature and density is such that as temperature increases, density decreases. This holds true for various substances, particularly in liquids and gases.


Explanation:

As the temperature increases, the density decreases for many substances, especially liquids and gases, due to the expansion of volume. This relationship is important to understand how temperature affects density in different states of matter.

For example, at the melting point of a substance, if pressure is increased, the melting point can be affected due to changes in density. Additionally, the density of air decreases with altitude due to less air pressure and weaker gravity at higher altitudes.
