Pressure in a Fluid

When a large bubble rises from bottom of a water lake to its surface, then its radius doubles. If the atmospheric pressure is equal to the pressure of height $H$ of a certain water column then the depth of lake will be

Show answer and solution

Answer: (c)

Radius doubles, so volume becomes $8V$ . At constant temperature, $P_1V_1 = P_2V_2$ .
In water-column units: $(H + h)V = H\times8V$
$h = 7H$
So the answer is (c) $7H$ .
