Hydrogen gas and oxygen gas have volume `1 cm^(3)` each at N.T.P. select incorrect statement/statements

Options

A. Number of molecues is same in both the gases
B. The rms velocity of molecules of both the gases is the same.
C. The internal energy of each gas is the same.
D. The average velocity of molecules of each gas is the same.

Answer

B

Explanation

At NTP same volume means same molecules `:' f_(1)=f_(2)`, so same temperature means same internal energy `(U=f/2 nRT)`. Average velocity is zero.
