Particle model — practice question

In one experiment, the volume of a gas in a cylinder is recorded while the gas pressure is increased. The readings obtained are listed below. Pressure $P/\text{Pa}$: $1.0\times10^5$, $2.0\times10^5$, $3.0\times10^5$, $4.0\times10^5$ Volume $V/\text{m}^3$: $20\times10^{-5}$, $10\times10^{-5}$, $6.0\times10^{-5}$, $4.0\times10^{-5}$ Suggest a possible explanation for these results?

  • AAfter the pressure is doubled, gas starts leaking into the cylinder.
  • BAfter the pressure is doubled, gas starts leaking out of the cylinder.
  • CThe temperature of the gas is constant.
  • DThe temperature of the gas is increasing.
