The helium and argon are put in the flask at the same room temperature ( 300 K). The ratio of average kinetic energies (per molecule) of helium and argon is :
(Give : Molar mass of helium $=4 \mathrm{~g} / \mathrm{mol}$ , Molar mass of argon $=40 \mathrm{~g} / \mathrm{mol}$ )

Question

The helium and argon are put in the flask at the same room temperature ( 300 K). The ratio of average kinetic energies (per molecule) of helium and argon is :
(Give : Molar mass of helium

=4 \mathrm{~g} / \mathrm{mol}

, Molar mass of argon

=40 \mathrm{~g} / \mathrm{mol}

)
