A gas mixture consists of molecules of types A, B and C with masses m_A > m_B > m_C  . Rank the three types of molecules in decreasing order of (a) average K.E., (b) rms speeds.

This is a short answer type question as classified in NCERT Exemplar

(a) The average KE will be the same

M= molar mass of the gas

m=mass of each molecular of the gas

R= gas constant

v_{rms $\propto \frac{1}{\sqrt[]{m}}$}

(b) k = Boltzmann constant

T= absolute temperature

m_A>m_B>m_C

V_rms.Arms.Brms.C
