Kinetic particle model of matter — practice question

A cube has edge lengths of $2.0\,\text{m}$. It contains a gas at a pressure of $8000\,\text{N m}^{-2}$. A second cube has edge lengths of $4.0\,\text{m}$. This cube contains the same mass of the same gas as the first cube, and is at the same temperature. What is the pressure of the gas in the second cube?

  • A$1000\,\text{N m}^{-2}$
  • B$4000\,\text{N m}^{-2}$
  • C$16\,000\,\text{N m}^{-2}$
  • D$64\,000\,\text{N m}^{-2}$
