Kinetic Theory of Gases

Real gases

Real gases deviate slightly from ideal gas laws because
=> Real gas molecules attract one another.
=> Real gas molecules occupy a finite volume.

`text(Real or Van der Waal's Gas Equation :)`

`(p + a/V^2)(V-b) = RT`

where a and b are called van der Waal's constants.

Pressure due to an ideal gas is given by:

`p= 1/3 (mn)/V . c^2 = 1/3 rho c^2.`

For one mole of an ideal gas

`p = 1/3 (M / V^2).c^2`
