The Maxwell-Boltzmann equation, which forms the basis of the kinetic theory of gases, defines the distribution of speeds for a gas at a certain temperature. The important features of Maxwell distribution of velocities are: (i) The fraction of molecules with very low or high velocities is very small. (ii) The fraction of molecules possessing higher velocities goes on increasing till it reaches the peak and further it starts decreasing.The fraction of molecules when the u=0, isThe molecules which have Very high u areIf T increases then the molecules with high u value
