Particle model — practice question

A gas syringe holds a gas volume $V_1$ at pressure $p_1$. Its volume is decreased to $V_2$ with no change in temperature. What expression gives the change in pressure?

  • A$\frac{p_1 V_1}{V_2} + p_1$
  • B$p_1 + \frac{p_1 V_2}{V_1}$
  • C$\frac{p_1 V_1}{V_2} - p_1$
  • D$\frac{p_1 V_2}{V_1} - p_1$
