Question 14

A marine biologist is studying gas bubbles in a deep freshwater lake.

A bubble released from the lake bed has an initial volume, $V_1$ , of $litres0.80\text{ litres}$ , at a pressure, $P_1$ , of $atmospheres4.20\text{ atmospheres}$ .

The bubble rises towards the surface of the lake, where the pressure, $P_2$ , is $atmospheres1.20\text{ atmospheres}$ .

Calculate the volume, $V_2$ , of the bubble near the surface.

Use the equation:

V_2 = \frac{P_1 \times V_1}{P_2}
