A cylindrical tube of a length of 30 cm is partitioned by a tight-fitting separator. The separator is very weakly conducting and can freely slide along the tube. Ideal gases are filled in the two parts of the vessel. In the beginning, the temperatures in parts A and B are 400 K and 100 K respectively. The separator slides to a momentary equilibrium position shown in the figure. Find the final equilibrium position of the separator, reached after a long time.
  • a)
    25 cm from right end
  • b)
    10 cm from right end
  • c)
    10 cm from left end
  • d)
    20 cm from left end
Correct answer is option 'C'. Can you explain this answer?

Calculation:
  • The middle wall is weakly conducting. Thus after a long time, the temperature of both parts will equalize.
  • The final position of the separating wall is at a distance x from the left end. So it is at a distance of 30 - x from the right end Putting the combined gas equation of one side of the separating wall,


⇒ 30 - x = 2x 
⇒ 3x = 30 
⇒ x = 10 cm
The separator will be at a distance of 10 cm from left end.
