Redirected from Charles law
The law, expressed in symbols, is:
Where V is the volume, T the temperature, and k is a constant. The volume is expressed in litres and the temperature in kelvin when using units.
To maintain the constant during heating of a gas, at fixed pressure, requires that the volume 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:
