Boyle's Law Experiment Aim To show that Pressure is proportional to the inverse to volume Method A gas syringe was attached to a pressure sensor. The pressure sensor was calibrated, assuming the atmospheric pressure at the time of the experiment was 100kPa. Differing volumes of gas were created in the gas syringe and they were recorded as were the corresponding values of pressure at that particular volume. The volume was varied between 20cm3 and 75cm3. …

…as this would not have been precise. As the reading of volume was read off using eye-sight a parallax error would have been produced. We can say that an uncertainty of ±1cm3 could have been introduced into the values of volume recorded, therefore producing an maximum uncertainty of 5%. This is a far more substantial uncertainty and as it would be systematic it could have altered the position of the lines plotted on the two graphs.
