(i) Some volume of a gas is trapped by concentrated sulphuric acid in the narrow tube. Water is heated and the volume (length) H of the trapped air increases as temperature are T rises. Values of length (volume) of air and corresponding values of temperature are tabulated. A graph of volume against temperature is plotted. The graph is a straight line cutting T at -273oC, showing that volume is directly proportional to absolute temperature.
(ii) - The experiment can only be carried out for a short temperature range
- Keeping the pressure constant is difficult
