Question

The diagram given below shows three glass chambers that are connected by valves of negligible volume. In an experiment, the valves are closed and initially the chambers contain the gases as given in the diagram. All the chambers are at fixed temperature of 300K.

Whihc of the following is correct relation between the average velocity of gas molecule in chamber A and B before valve-1 is opened.
A. `V_(A)=V_(B)`
B. `V_(A)ltV_(B)`
C. `V_(A)gtV_(B)`
D. insufficient information

Answer 1

`v propsqrt((T)/(M))`
since T is constant
`v prop sqrt((T)/(M))`
`v_(He)gtH_(N_(2))` or `v_(A)gtv_(B)`
