Charles' law

Principle

The ideal gas equation describes the thermal state of an enclosed gas with regard to the parameters of state; pressure p, volume V, temperature T and number of gas molecules n. It enables three different gas laws to be derived, each for the behaviour of a gas, but with a different parameter of state held constant. Charles's law defines the dependence between temperature and volume at constant pressure. In this experiment, a volume of gas is enclosed in a gas syringe and the temperature of it is controlled by means of a water bath. The gas volume can be read from a scale at the same time as the temperature of
the it is measured.
