Question

Three closed vessels a, b and c are at the same temperature t and contain gases which obey maxwellian distribution of velocity. vessel a contains only o2;b only n2 and c a mixture of equal quantities of o2 and n2 if the average speed of o2 molecules in vessel a is v1, that of n2 molecules in vessel b is v2,, the average speed of o2 molecules is vessel c is

Answer 1

Answer is-
Average speed of molecule is given by -
V (max.) = √8kT/mπ
It will depend on the particle mass and temperature
Temperature will be same for all three vessels
Average velocity will be same for O2 in both of the vessels
So V1 will be the correct answer to given question.
