Determine the gas temperature at which (a) the root mean square velocity of hydrogen molecules exceeds their most probable velocity by `Delta v = 400 m//s` , (b) the velocity distribution function `F (v)` for the oxygen molecules will have the maximum value at the velocity `v = 420 m//s`.A. 384KB. 342KC. 300KD. 280K

Answer» Correct Answer - A
`v_(rms)-v_(P)=(sqrt(2)-sqrt(2))sqrt((RT)/(M))=Deltav`
`thereforeT=(M)/(R)((Deltav)/(sqrt(3)-sqrt(2)^(2)))=384k`
