Question

At a definit temperature (T), the distribution of speeds is given by the curve. In the curve points A, B and C indicates the speeds corresponding to :

A. most probable, average and root mean square speeds
B. average, root mean square and most probable speeds
C. root mean square, average and most probable speeds
D. most probable, root mean square and average speeds

Answer 1

Correct Answer - a
(a) `U_("rms")=sqrt((2RT)/(M)) " "U_("avg")=sqrt((8)/(pi)(RT)/(M)) " "U_("mp")=sqrt((2RT)/(M))`
`underset (1.224)(U_("rms"))" : "underset(1.128)(U_("avg"))" : "underset(1)(U_("mp"))`
`U_("rms")gtU_("avg")gtU_("mp")`
