Thermodynamics

Two flasks \(A\) and \(B\) have equal volumes. \(A\) is maintained at \(300 \mathrm{~K}\) and \(B\) at \(600 \mathrm{~K}\). Equal masses of \(\mathrm{H}_2\) and \(\mathrm{CO}_2\) are taken in flasks \(A\) and \(B\) respectively. Find the ratio of total KE of gases in flask \(A\) to that of \(B\).
