A gas consisting of diatomic molecules is at temperature of 117°C. if the moment of inertia of each molecule about an axis passing through the centre and normal to the molecular axis is 1.5 xx 10^(-40) "kgm"^(2). then the root mean square angular speed of each molecule is: (Boltzmann's constant k=1.38 xx 10^(-21) J//K )
