An animation of an experiment demonstrating Charles' Law. A volume of gas is heated and the volume and temperature recorded in a table.

An animation plotting a graph of volume against temperature to illustrate Charles' Law. The results from Charles' Law are presented in a table. Plotting the results in a volume-temperature graph.

An animation illustrating the volume-temperature graph for a gas. The units on the temperature scale of the graph from Charles' Law 2 are converted from Celsius to Kelvin and the graph extrapolated to absolute zero.  

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 ofCharles's law is: When the pressure on a sample of a dry gas is held constant, the Kelvin temperature and the volume will be directly related.

Also known as the law of volumes, Charles's Law is an experimental gas law which describes how gases tend to expand when heated. It was first published by French natural philosopher Joseph Louis Gay-Lussac in 1802, although he credited thediscovery to unpublished work from the 1780s by Jacques Charles, hence the name.

For a fixed amount of an ideal gas kept at a fixed temperature, pressure and volume are inversely proportional. Or Boyle's law is a gas law, stating that the pressure and volume of a gas have an inverse relationship, when temperature is held constant.

If the volume of a container is decreased, the temperature decreases. Suppose thetemperature is increased. This means gas molecules will move faster and they will impact the container walls more often. This means the gas pressure inside the container will increase (but only for an instant.

Charles' law states: "For a fixed mass of gas, at a constant pressure, the volume (V) is directly proportional to the absolute temperature (T)." ... If the internal pressure increases the piston will move up to allow the pressure to equalise.

Charles' Law: The Temperature-Volume Law. This law states that the volume of a given amount of gas held at constant pressure is directly proportional to the Kelvin temperature. As the volume goes up, the temperature also goes up, and vice-versa.

Pressure and volume are inversely proportional to each other. This means that as the pressure decreases, the volume increases, and as the pressure increases, thevolume decreases. One way to think of this is if you push on a gas by decreasing itsvolume, it pushes back by increasing its pressure.

One way to think of this is if you increase the speed of the molecules –by increasing their temperature- the force of the molecules hitting their container increases and this increases the pressure. This relationship is called Gay-Lussac's Law and makes up part of the ideal gas law.
