प्रश्न
A gas mixture consists of molecules of types A, B and C with masses mA > mB > mC. Rank the three types of molecules in decreasing order of rms speeds.
उत्तर
As k = Boltzmann constant
T = Absolute temperature (same for all)
But mA > mB > mC
(vrms)A < (vrms)B < (vrms)C
∴ or (vrms)C < (vrms)B < (vrms)A
