1.	2 ala 2 on a day when the atmospheric pressure is 750 mm Hg2Atwhat temperature would CO2 molecules have a n mns speed equal to thatof H2 molecules at 25°C?03nt mean square average and
Answer» square root of 3kT/M, so this question is based on the mass ratio. for He, the rms speed is = sqrt of 3k(273+25)/4for CO2, the same rms speed is = sqrt of 3kT/44 (298)/4 = T/44; T = 3278 K

Answer»

square root of 3kT/M, so this question is based on the mass ratio.

for He, the rms speed is = sqrt of 3k(273+25)/4for CO2, the same rms speed is = sqrt of 3kT/44

(298)/4 = T/44; T = 3278 K
