The total average kinetic energy of all the molecules of a gas is proportional to its absolute temperature (T).

Hence, the denser the gas, the slower is the rate of diffusion.Īccording to this law, the resultant pressure exerted by a mixture of non-interacting gases is equal

It states that the rate of diffusion of a gas is inversely proportional to the square root of the density of the gas. contain the same number of molecules equalling 6.023 x 1023. Where n is the number of moles of the enclosed gas and R is the molar gas constant which is the same for all gases and its value isĮqual volumes of all gases under S.T.P. The relationship between pressure P, volume V and absolute temperature T of a gas is called its equation of state. The temperature of the gas provided the pressure of the gas remains constant.Īccording to this law, the pressure P of a given mass of a gas is directly proportional to its absolute temperature T, provided the volume V of the gas remains constant. According to the kinetic theory, the pressure P exerted by an ideal gas is given byĪccording to this law, the volume (V) of a fixed mass of a gas is inversely proportional to the pressure (P) of the gas, provided the temperature of the gas is kept constant.Īccording to this law, the volume (V) of a given mass of a gas is directly proportional to the

The pressure of a gas is the result of the continuous bombardment of the gas molecules against the walls of the container. (ii) There is no force of attraction or repulsion amongst the molecules of the gas. (i) Molecule of an ideal gas is a point mass with no geometrical dimensions. Kinetic theory explains the behavior of gases based on the idea that gas consists of rapidly moving atoms or molecules.Īn ideal gas or a perfect gas is that gas that strictly obeys gas laws such as Boyle’s law, Charle’s law, Gay Lussac’s law, etc.Īn ideal gas has the following characteristics:
