Question

If `T_(1),T_(2)` and `T_(3)` are the temperatures at which the `u_("rms"),u_("average"),u_("mp")` of oxygen gas are all equal to 1500 m/s then the correct statement is :
A. `T_(1)gtT_(2)gtT_(3)`
B. `T_(1)ltT_(2)ltT_(3)`
C. `T_(1)=T_(2)=T_(3)`
D. None of these

Answer 1

Correct Answer - b
(b) `U_("mp")=sqrt((2RT)/(M))`
`U_("avg")=sqrt((8)/(pi)(RT_(2))/(M))`
`U_("rms")=sqrt((RT_(1))/(M))`
`T_(3)gtT_(2)gtT_(1)`
