1 mol of `N_(2)` & 3 mol of `O_(2)` are kept in two different containers with a volume of V at a fixed temperature. Compare-(i) the average kinetic energy (ii) the total kinetic energy of the molecules.

Explanation

(i) The average kinetic energy of gas molecules depends only on the absolute temperature of the gas. Since both the gases are at the same temperature, they will have equal average kinetic energy.
(ii) At T K, the total kinetic energy of n mol gas molecules`=nxx(3)/(2)`RT. hence, at T K, the total kinetic energy of 3 mol `O_(2)` molecules is 3 times that of 1 mol `N_(2)` molecules.
