Условие
The volume of an air bubble becomes three times greater as it rises from the bottom to the top of a lake. What is the depth of the lake if its temperature is constant? Atmospheric pressure is measured to be $100 \text{ kPa}$ and the density of water is $1000 \text{ kg/m}^3$.
The image shows a cross-section of a lake with an air bubble. At the bottom of the lake, at depth $h$, the bubble has volume $V_2$ and pressure $P_2$. As it rises to the surface, its volume expands to $V_1$ at pressure $P_1$. Arrows indicate pressure vectors $P_1$ at the surface and $P_2$ at depth $h$.
