Vedclass · Answer

(A) The average kinetic energy $(E)$ for $1 \ mol$ of an ideal gas is given by $E = \frac{3}{2}RT$.From this,we can express $RT$ as $RT = \frac{2E}{3}$.The formula for root mean square velocity $(U_{rms})$ is $U_{rms} = \sqrt{\frac{3RT}{M}}$,where $M$ is the molar mass.Substituting the value of $RT$ into the $U_{rms}$ formula:$U_{rms} = \sqrt{\frac{3}{M} 	imes \frac{2E}{3}}$$U_{rms} = \sqrt{\frac{2E}{M}}$$U_{rms} = (\frac{2E}{M})^{1/2}$.

For $1 \ mol$ of a gas,the average kinetic energy is $E$. Then the root mean square velocity $U_{rms}$ of the gas is:
