Question

A ring shaped tube contain two ideal gases with equal masses and relative molar masses `M_1=32 and M_2=28.`
The gases are separated by one fixed partiotin and another movable stopper S which can move freely without friction inside the ring. The angle `alpha` as shown in the figure is ...... degrees.

A. `291^(0)`
B. `219^(0)`
C. `125^(0)C`
D. `192^(0)C`

Answer 1

Correct Answer - D
`(alpha)/(2pi - alpha) = (n_(1))/(n_(2))` and `(n_(1))/(n_(2)) = (M_(2))/(M_(1))` and `n = (m)/(M)`
