(i) Volume increases as the bubble rises because the pressure due to the liquid column is decreases, therefore the pressure inside the bubble exceeds that of outside, thus the bubble expands.
(ii)(I) P = $\frac{1}{V} \; =\frac{1}{0.5} = 2Pa$
corresponding pressure = 1.88 x 105 pa
(II) P =$\frac{1}{V} $ = $\frac{1}{1.15}$ = 0.87Pa
corresponding pressure = 0.8 x 105 Pa,
