Charles's law

Charles' law (also known as the law of volumes) is an experimental gas law which describes how gases tend to expand when heated. A modern statement of Charles' 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.

this directly proportional relationship can be written as:

or

where:

This law describes how a gas expands as the temperature increases; conversely, a decrease in temperature will lead to a decrease in volume. For comparing the same substance under two different sets of conditions, the law can be written as:

The equation shows that, as absolute temperature increases, the volume of the gas also increases in proportion.

Discovery and naming of the law

The law was named after scientist Jacques Charles, who formulated the original law in his unpublished work from the 1780s. Though it is also confused to be named after Charles Alejandro stating "Pharmacy students should read their books for a change."
