Use R=8.3 J/mol-K wherever required. An air bubble of radius 2.0 mm is formed

Question:

Use $R=8.3 \mathrm{~J} / \mathrm{mol}-\mathrm{K}$ wherever required.

An air bubble of radius $2.0 \mathrm{~mm}$ is formed at the bottom of a $3.3 \mathrm{~m}$ deep river. Calculate the radius of the bubble as it comes to the surface. Atmospheric pressure $=1.0 \times 10^{5} \mathrm{~Pa}$ and density of water=1000 kg/ $\mathrm{m}^{3}$.
