Question

How are the density and temperature of air related?

Answer 1

Density and Temperature of air are Inversely Proportional

According to Charles' Law, the temperature and volume of a gas are directly proportional. As one rises, so does the other. Because density is mass/volume, when temperature or volume increases, the density decreases.

Answer 2

Charles's Law states that temperature and volume are directly proportional, so as temperature goes up so does volume. ... So as volume goes up (with constant mass) density will lower. Therefore, as temperature goes up density goes down.
