Theory & Objective
Verify that for a fixed mass of dry gas at constant volume, the pressure (p) is directly proportional to its absolute temperature (T). Heat the water slowly while stirring continuously and record readings at intervals[cite: 1].

Record 6 sets of temperature and pressure readings as temperature rises by ~10 °C increments[cite: 1].
