Charles's law

Uncommon card · No. 196695

Charles's law (also known as the law of volumes) is an experimental gas law that describes how gases tend to expand when heated. A modern statement of Charles's law is: When the pressure on a sample of a dry gas is held constant, the Kelvin temperature and the volume will be in direct proportion. This relationship of direct proportion can be written as: V ∝ T {\displaystyle V\propto T} So this means: V T = k , or V = k T {\displaystyle {\frac {V}{T}}=k,\quad {\text{or}}\quad V=kT} where: V is the volume of the gas, T is the temperature of the gas (measured in kelvins), and k is a constant for a particular pressure and amount of gas. This law describes how a gas expands as the temperature increases; conversely, a decrease in temperature...
