  • 3 Gas Laws
    • Boyle's Law
      • For a fixed mass of gas at constant temperature, its pressure X its volume is constant
      • A gas that obeys Boyle's Law is said to be an ideal gas.
      • pV = constant
    • Charles's Law
      • For an ideal gas at constant pressure, its volume is directly proportional to its absolute temperature.
      • Experiment: (Required prac 8)
        • Concentrated sulphuric acid in a capillary tube and heated in a large beaker of water
      • V/T = constant
    • Pressure Law
      • At constant volume, the pressure of an ideal gas is directly proportional to its absolute temperature
      • P/T = constant
      • Plot a graph of p against 1/V = STRAIGHT LINE!
