Which statements about a sample of gas containing molecules of different masses are true? check all that apply. a. more-massive gas molecules in the sample have lower rms speed than less-massive ones. b. more-massive gas molecules in the sample have higher rms speed than less-massive ones. c. the rms speed depends only on temperature, and so all types of particles in the sample have the same rms speed.
