Charles's law (sometimes called the Law of Charles and Gay-Lussac) is one of the The gas laws are a set of laws that describe the relationship between temperature, pressure and volume of gases. The laws include Boyles law, Charles law, Grahams law, Henrys law, and Avogadros law and they are collectively generalized by the universal gas equation, also known as... gas laws; it relates the volume and temperature of an An ideal gas (also called a perfect gas) is a hypothetical fluid consisting of particles that are identical to each other, occupy negligible volume and undergo perfect elastic collisions with each other, with no intermolecular forces and no intramolecular storage of energy, as opposed to a real gas, a gas... ideal gas held at a constant pressure. The law was first published by Joseph-Louis Gay-Lussac (December 6, 1778–May 10, 1850) was a French chemist and physicist. He is known mostly for two laws related to gases.

V is the Volume (also called capacity) is a quantification of how much space an object occupies. The SI unit for volume is the cubic metre (American spelling meter). The volume of a solid object is a numerical value given to describe the three-dimensional concept of how much space it occupies. One... volume (measured in The cubic metre (symbol m³) is the SI derived unit of volume. It is the volume of a cube with edges one metre in length.

k is a constant.

To maintain the constant during heating of a gas at fixed pressure, the volume must increase. Conversely, cooling the gas decreases the volume. The exact value of the constant need not be known to make use of the law in comparison between two volumes of gas at equal pressure:
