Answer:
B. The same as that for container A
Explanation:
To calculate the average Kinetic Energy per molecule,
[tex]K_{avg} = 3/2 K_{B} T[/tex]
Where [tex]K_{avg}[/tex] is the average kinetic energy per molecule and [tex]K_{B}[/tex] is the Boltzmann constant
From the above equation it is seen that [tex]K_{avg}[/tex] only depends on the temperature of the gas
And since the temperatures of both gases are equal, their average kinetic energy per molecule is the same
