The diagram represents a diver at a depth of $20\ \text{m}$ beneath the lake surface. At this depth, the total pressure is $3.0 \times 10^5\ \text{Pa}$. An air bubble has a volume of $0.60\ \text{cm}^3$ when it leaves the diver. It then travels up to the lake surface, where the pressure is $1.0 \times 10^5\ \text{Pa}$. The temperature of the air in the bubble stays constant. What is the volume of the air bubble at the surface of the lake?
- A$0.20\ \text{cm}^3$
- B$0.60\ \text{cm}^3$
- C$1.8\ \text{cm}^3$
- D$2.4\ \text{cm}^3$
