Two flasks A and B of equal volume containing equal masses of $H_{2}$ and $C H_{4}$ gases are at 100 K and 200 K temperature, respectively. Which of the following is true about the total KE (kinetic energy)?

Options:

Answer:

Solution:

Total KE $= K \bar{E}$ (per mole) $\times$ Moles of molecules
Total $K E_{A} = \frac{3}{2} R T_{A} n_{A}$
$n_{A} = \frac{m}{2}$
$n_{B} = \frac{m}{16}$
So $\frac{n_{A}}{n_{B}} = 8$
So $\frac{T o t a l K E_{A}}{T o t a l K E_{B}} = \frac{T_{A} N_{A}}{T_{B} N_{B}} = \frac{1}{2} \times 8 = 4$ .
