Energy and root mean square velocity question

[QUOTE="Krushnaraj Pandya, post: 6075196, member: 646372"] Alright, I understand. Thank you very much for explaining this :D there's a numerical in my book which seems to have a discrepancy though (from which my question on this post arised). Its as follows- "calculate the rms speed of an ideal diatomic gas having molecular weight 32 gm/mol at 273 K If Cp=9.3 J/mol K and Cv=6.34 J/mol K" Using Cp-Cv=R and putting it into the equation ##V_{rms} = \sqrt{\frac{3RT}{M}}## gives an incorrect answer while plugging it into ##V_{rms} = \sqrt{\frac{5RT}{M}}## gives the correct one. Is this a mistake on the part of the book? [/QUOTE]
