    An air bubble is released from the bottom of a pond and is found to expand to thrice its original volume as it reached the surface. If the atmospheric pressure is 100 kPa, the absolute pressure at the bottom of lake in kPa is ...(assume no temperature variation):

    A)  33.3                      

    B)         50.0                      

    C)  100.0                   

    D)         200.0

    E)  300.0

    Correct Answer: E

    Solution :

            \[PV=constant\] \[\Rightarrow \]               \[(h\rho g)V=100\times {{10}^{3}}\times 3V\] \[\Rightarrow \]               \[hpg=\]absolute pressure\[=300\text{ }kPa\]
