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 different

B

The internal energy of each gas is same since the temperature is same.

C

The number of molecules is same in both the gases

D

The average speed of Helium molecules is greater then hydrogen molecules.

Text Solution

Verified by Experts

The correct Answer is:
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.
