OBJECT: To study the expansion of gases, to check Charles’ Law and to measure the temperature coefficient of pressure increase of dry air at Constant volume.
METHOD: Charles’ Law for the expansion of gases is studied by the use of a simple form of constant-volume air thermometer. A fixed volume of dry air is subjected to certain measured temperatures and the corresponding pressures observed. From the resultant pressure-temperature curve the temperature coefficient of pressure increase at constant volume is determined. By extrapolating this curve the value of “absolute zero” is determined approximately.
