Kinetic particle model of matter — practice question

At the base of a lake, an air bubble occupies a volume of $2.0\,\text{cm}^3$ when the total pressure is $4.0 \times 10^5\,\text{Pa}$. The water temperature in the lake stays constant. The atmospheric pressure at the water surface is $1.0 \times 10^5\,\text{Pa}$. What volume does the bubble have after it reaches the surface?

  • A$0.13\,\text{cm}^3$
  • B$0.17\,\text{cm}^3$
  • C$6.0\,\text{cm}^3$
  • D$8.0\,\text{cm}^3$
