Charles law is an experimental gas law which describes how gases tend to expand when heated.
Charles law states: The volume of a given mass of a gas is directly proportional to its temperature (measured in Kelvin the absolute temperature scale). If pressure and the amount of gas remain constant; the law states, the volume of the gas increases or decreases by the same factor as its temperature change.
`T_1` -initial temperature of the gas
`T_2` - final temperature of the gas
`V_1` - Initial volume of the gas before the temperature change
The law was named after scientist Jacques Charles, who formulated the original law in his unpublished work from the 1780s.
Remember to input temperatures in degrees Kelvin: K = C + 273
