When using a manometer to check Boyle's Law, the pressure is changed slowly to avoid changing the gas temperature. Boyle's Law states that the pressure of a given mass of gas is inversely proportional to its volume at constant temperature. If the pressure is changed too quickly, it can cause a change in temperature due to rapid compression or expansion, which would violate the condition of constant temperature and affect the accuracy of the results. Therefore, changing the pressure slowly helps ensure that the temperature remains constant during the experiment.
