One mole of neon (atomic mass = $$20\ \text{g mol}^{-1}$$) and one mole of argon (atomic mass = $$40\ \text{g mol}^{-1}$$) are stored in two separate containers I and II, at temperature $$T$$ and $$2T$$ respectively. If both the gases are assumed to behave ideally

K.E. and average velocity of the gas molecules will be the same in both I and II

K.E. and average velocity of the gas molecules in II will be twice that of the gas molecules in I

K.E. of the gas molecules in II will be twice that in I and average velocity of the gas molecules in both I and II will be the same

Both K.E. and average velocity of the gas molecules in I will be twice that of the gas molecules in II
