How does Charles' law relate to density?

Answer 1

Charles' law is also known as the law of volumes. It states that the volume of a gas will expand when heated. This means that as gas is heated, its density lowers, because the same number of molecules now occupy a greater space.

Answer 2

Charles's Law (for Jacques Charles, 1746-1823) states that the volume of a gas increases with an increase in temperature.

(This applies where a gas is maintained at a set pressure. Otherwise, within a confined volume, increased temperature increases pressure, as under Boyle's Law, volume and pressure are inversely proportional.)

Answer 3

Charles' law states that for a fixed amount of gas at a constant pressure, the volume of the gas is directly proportional to its temperature. As temperature increases, the volume of the gas also increases. This relationship affects the density of the gas because as volume increases with temperature, the density decreases since density is mass/volume.
