A marine biologist is studying gas bubbles in a deep freshwater lake.
A bubble released from the lake bed has an initial volume, V1V_1V1, of 0.80 litres0.80\text{ litres}0.80 litres, at a pressure, P1P_1P1, of 4.20 atmospheres4.20\text{ atmospheres}4.20 atmospheres.
The bubble rises towards the surface of the lake, where the pressure, P2P_2P2, is 1.20 atmospheres1.20\text{ atmospheres}1.20 atmospheres.
Calculate the volume, V2V_2V2, of the bubble near the surface.
Use the equation:
V2=P1×V1P2 V_2 = \frac{P_1 \times V_1}{P_2} V2=P2P1×V1
