5054Particle model
A gas syringe contains a volume V₁ of gas at pressure p₁. The volume is reduced to V₂ without any change of temperature. What is the expression for the change in pressure?
- A\frac{p_1 V_1}{V_2} + p_1
- Bp_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
