Two identical storage tanks are filled with a gas. Both gases are at STP . If one tank contains Helium (Atomic no 2) and the other Neon (Atomic no 10). If average kinetic energy of Helium is "2E". Then the average kinetic energy of Neon is:
10E
2E
6E
0.2 E
Unpredictable

KE = 3/2(k)(T) where k is Boltzmann constant and T is temp in Kelvin. Thus KE is only dependent on the temperature and KE will be equal at equal temperature.And its given that both are at STP. Thus, KE of Helium=KE of Neon = 2E
