1. Boyle's LawFor a fixed mass of gas, the pressure is inversely proportional to its volume provided the temperature is kept constant. pV = constant This can be…
2. Charles' LawIt can be shown, using a glass tube open at one end containing dry air trapped in the tube by a suitable liquid, that for a fixed mass of gas, the…
3. Pressure LawFor a fixed mass of gas of constant volume, the pressure is directly proportional to the absolute temperature (in kelvin) or p/T = constant If a…
4. The Ideal Gas EquationSmoke particles may be illuminated and observed under a microscope.
5. Kinetic Theory of GasesThe molecules of an ideal gas have a range of speeds.
