Which statements about a sample of gas containing molecules of different masses are true?

Which statements about a sample of gas containing molecules of different masses are true?

Check all that apply.

	The rms speed depends only on temperature, and so all types of particles in the sample have the same rms speed. More-massive gas molecules in the sample have lower rms speed than less-massive ones. More-massive gas molecules in the sample have higher rms speed than less-massive ones.
