States of matter — practice question

A $10.0\,\text{cm}^3$ bubble of an ideal gas is produced on the sea bed, where the pressure is $2020\,\text{kPa}$. Immediately below the sea surface, the pressure is $101\,\text{kPa}$ and the temperature is the same as at the sea bed. What volume does the bubble have when it reaches just below the sea surface?

  • A$10.0\,\text{cm}^3$
  • B$20.2\,\text{cm}^3$
  • C$200\,\text{cm}^3$
  • D$2\,020\,000\,\text{cm}^3$
