Particle model — practice question

Air at a pressure of $1.0 \times 10^{5}\,\text{N m}^{-2}$ is held in a container by a piston. A force is used to push the piston downward into the container. The temperature of the air stays constant. The distance from the base of the container to the piston falls from $0.18\,\text{m}$ to $0.15\,\text{m}$. What is the new air pressure inside the container?

  • A$0.69 \times 10^{5}\,\text{N m}^{-2}$
  • B$0.83 \times 10^{5}\,\text{N m}^{-2}$
  • C$1.2 \times 10^{5}\,\text{N m}^{-2}$
  • D$1.4 \times 10^{5}\,\text{N m}^{-2}$
