- Boyle's LawFor a fixed mass of gas, the pressure is inversely proportional to its volume provided the temperature is kept constant.e. pV = constant This can be…
- 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…
- Pressure LawFor a fixed mass of gas of constant volume, the pressure is directly proportional to the temperature or p/T = constant If a graph of pressure…
