A gas mixture consists of molecules of type 1, 2 and 3 with molar masses 
and 
are the rms speed and average kinetic energy of the gases. Which of the following is true?
A
and 
B
and 
C
and 
D
and 
Text Solution
Verified by ExpertsThe correct answer is:
A
The rms speed depends upon the molecular mass as 
,
However, the kinetic energy does not depend on the mass. It depends only on temperature of an ideal gas.
Since we have 
, we get
However, 
.
