Three closed vessels A, B, and C are at the same temperature T and contain gases which obey the Maxwellian distribution of velocities. Vessel A contains only O 2 , B only N 2 and C a mixture of equal quantities of O 2 and N 2 . If the average speed of O 2 molecules in vessel A is V 1 , that of the N 2 molecules in vessel B is V 2 , the average speed of the O 2 molecules in vessel C will be :
A
(V 1 + V 2 )/2
B
V 1
C
(V 1 V 2 ) 1/2
D
Text Solution
Verified by ExpertsThe correct answer is:
B
V av = 
, V AV α 
For same temp in vessel A, B and C, Average speed of O 2 molecule is same in vessel A and C and is equal to V 1 .
