Question
A ring shaped tube contains two ideal gases with equal masses and atomic mass numbers M1 = 32 and M2 = 28. The gases are separated by one fixed partition P and another movable conducting partition S which can move freely without friction inside the ring. The angle a as shown in the figure (in degrees) in equilibrium is:


Options
A.
B.
C.
D.
Solution
P1 = P2 [In equilibrium]
T1 = T2 ⇒
⇒ 
⇒ M1(2π − α) = M2 α
or a =
T1 = T2 ⇒
⇒ M1(2π − α) = M2 α
or a =
