The general gas equation describes the relationship between pressure, volume and temperature of an enclosed gas volume. A gas syringe is used for measuring the relationship between the volume and the pressure, which is sealed with the help of motor oil. In addition to this, the gas syringe is also tempered with the help of a water bath. This waterbath helps to avoid the temperature fluctuations during compression and expansion and also enables one to record isotherms at different temperatures. Volume, (number of the measurement value), pressure and temperature are recorded as points upon a key press.
