"v_{rms}=\\sqrt{\\frac{3RT}{M}}"


At "20\u00b0C(293K)" "v_{rms1}=\\sqrt{\\frac{3R\\cdot293}{M}}"


At "80\u00b0(353K)" "v_{rms2}=\\sqrt{\\frac{3R\\cdot353}{M}}"


"\\frac{v_{rms1}}{v_{rms2}}=\\sqrt{\\frac{293}{353}}\\to v_{rms2}=v_{rms1}\/\\sqrt{\\frac{293}{353}}="



"=\\frac{550}{0.911}=604m\/s"
