The correct answer is:
$1:1$
(a) The average kinetic energy of molecules is given by
$\mathrm{KE}_{\mathrm{av}}=\frac{3}{2} K T$. So it depends only on temperature
$\mathrm{KE}_1: \mathrm{KE}_2=1: 1$
$\mathrm{KE}_{\mathrm{av}}=\frac{3}{2} K T$. So it depends only on temperature
$\mathrm{KE}_1: \mathrm{KE}_2=1: 1$
