#### Gas Laws:

Gas

In gases the intermolecular forces are very weak and its moleculers may fly apart in all directions

Boyle’s law : For a given mass of an ideal gas at constant temperature the volume of a gas is inversely proportional to its pressure.

(2) Charle’s law: For the pressure remaining constant, the volume of the given mass of a gas is directly proportional to its absolute temperature.

(3) Gay-Lussac’s law or pressure law: The volume remaining constant, the pressure of a given mass of a gas is directly proportional to its absolute temperature.

(4) Avogadro’s law : Equal volume of all the gases under similar conditions of temperature and pressure constain equal number of molecules, i.e., N1 = N2.

(5) Grahm’s law of diffusion : When two gases at the same pressure and temperature are allowed to diffuse into each other, the rate of diffusion of each gas is inversely proportional to the suare root of the density of the gas,

(6) Dalton’s law of partial pressure: The total pressure exerted by a mixture of non-reacting gases occupying a vessel is equal to the sum of the individual pressures which each gases exert if it alone occupied the same volume at a given temperature.
