METHOD We pumped air into the tube until the pressure was as high as possible, which was 3.4x105 Pa. We recorded the volume of gas; it was 16.0cm3. We then let the pressure down slightly and recorded the pressure and volume again. We repeated this about 15 more times, which was when the pressure reached 1.03x105 Pa. Here are the results: Gas Pressure (x105 Pa) Gas Volume (cm3) 3.4 16 3.23 16.9 3.09 17.8 2.91 18.8 2.78 19.7 2.62 21 2.48 22.1 2.31 23.7 2.15 25.7 1.97 28.1 1.73 31.9 1.6 34.9 1.41 39.1 1.28 43.3 1.12 50 1.03 56 EXPLANATION Boyle¡¦s law states that the volume of a fixed mass of ideal gas at constant temperature is inversely proportional to the gas pressure: P "f 1/v OR pv = constant This means that if p is doubled then v is halved, or, if p is halved then v is doubled. MOLECULAR EXPLANATION At room temperature and pressure, there are a certain number of gas molecules in 10cm3 of air. Each molecule exerts a...
