An air bubble of volume 
is released by a fish at a depth h in a lake. The bubble rises to the surface. Assume constant temperature and standard atmospheric pressure P above the lake. The volume of the bubble just before touching the surface will be (density of water is ρ ρ )
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
According to Boyle’s law multiplication of pressure and volume will remains constant at the bottom and top.
If P is the atmospheric pressure at the top of the lake and the volume of bubble is V then from 
⇒ ⇒ 
∴ ∴
