Passage / Comprehension
A glass tube AD of uniform cross-section of length 56 cm contains two columns of air (assume ideal behaviour) AB and CD, separated by a column of mercury (BC) of length 8 cm. When the tube is horizontal, AB = 20 cm and CD = 28 cm. When the tube is held vertically with the end 'A' up, the mercury column moves down 10 cm.
Which of the following information regarding the tube is correct?
Options:
Answer:
B
Solution:
With A up, mercury moves down 10 cm: AB 20 30, CD 28 18. Both air columns change volume, so both must be trapped; both ends are closed. Consistent with Q8. Hence (b).
