A glass tube of uniform internal radius ...

A glass tube of uniform internal radius `(r)` has a valve separating the two identical ends. Initially, the valve is in a tightly closed position. End `1` has a hemispherical soap bubble of radius `r`. End `2` has sub-hemispherical soap bubble as shown in figure. Just after opening the valve.

A

Air from end 1 flows towards end 2. No change in the volume of the soap bubbles

B

Air from end 1 flows towards end 2. Volume of the soap bubble at end 1 decreases

C

No change occurs

D

Air from end 2 flows towards end 1. Volume of the soap bubble at end 1 increases
