Practice JEE Main Kinetic Theory in the app →The root-mean-square (rms) speed of gas molecules is given by:The mean translational kinetic energy of one molecule of an ideal gas at temperature $T$ is:A diatomic ideal gas (e.g. $\mathrm{O_2}$, $\mathrm{N_2}$) at room temperature has degrees of freedom (translaIf the absolute temperature of an ideal gas is doubled, the rms speed of its molecules:The mean free path $\lambda$ of a gas molecule of diameter $d$ at number density $n$ is approximately:For an ideal gas, the relationship between $C_p$ and $C_v$ is (Mayer's relation):A balloon at STP contains $1$ mol of ideal gas. Using $R = 8.314$ J/(mol K) and $T = 273$ K, the product $PV$ A jar of gas is heated so its absolute temperature doubles. The average kinetic energy per molecule:A monatomic ideal gas has degrees of freedom $f = 3$. Its molar specific heat at constant volume is:A diatomic ideal gas has $C_v = \tfrac{5}{2}R$. Its $C_p$ and ratio $\gamma$ are:
