Various gas laws were given time to time to explain the behaviour of gases.
1. Boyle’s law: The volume of given mass of a gas is inversely proportional to pressure at constant constant temperature.
2. Charles law: The volume of given mass of a gas is directly proportional to absolute temperature at constant pressure.
V~T (at constant mass and P)
3. Gay-Lussacs law or pressure temperature law: The pressure of a given mass of a gas is directly proportional to temperature at constant volume.
3.The Gas equation:
PV=RT for one mole of gas
And PV=nRT For n mole of gas
Where R is molar gas constant, w is weight of gas and m is molecular weight of gas.
