Question: A spherical air bubble in a lake expands as it rises slowly to the surface. At the point it starts to rise, the pressure is

A spherical air bubble in a lake expands as it rises slowly to the surface. At the point it starts to rise, the pressure is $2.00 \mathrm{~atm}$, the temperature of the water is $10.0^{\circ} \mathrm{C}$, and the radius of the bubble is $5.00 \times 10^{-3} \mathrm{~m}$. At the surface, the pressure is $1.00 \mathrm{~atm}$ and the temperature of the water is $20.0^{\circ} \mathrm{C}$.

(a) What is the final-to-initial volume ratio for the expanding bubble?

(b) What is the change in thermal energy of the bubble?
