A Hydrogen gas and a helium gas each having volume `100cm^(3)` at `NTP

1.	A Hydrogen gas and a helium gas each having volume `100cm^(3)` at `NTP` are enclosed in separate containers. Choose the correct option(s)A. The RMS velocity of molecules of the gases is differentB. The internal energy of each gas is same since the temperature is same.C. The number of molecules is same in both the gasesD. The average speed of Helium molecules is greater then hydrogen molecules.
Answer» Correct Answer - A::C `V_(rms)=sqrt((3RT)/(M))`, since M different therefore `V_(rms)` is different Since P,T,V are same then no. of molecules is same.
