A student traps a sample of gas inside a sealed syringe.
The initial pressure of the gas (P1P_1P1) is 110 kPa.
The initial volume of the gas (V1V_1V1) is 150 cm3.
The syringe plunger is slowly pushed in, keeping the temperature of the gas constant.
The new volume of the gas (V2V_2V2) is 60 cm3.
Calculate the new pressure of the gas, P2P_2P2.
Use the equation:
P2=P1×V1V2 P_2 = \frac{P_1 \times V_1}{V_2} P2=V2P1×V138 exam-style questions on Edexcel GCSE Physics 14.3 Gas pressure and temperature, covering 14.3.1 Gas pressure and particle motion, 14.3.2 Temperature and pressure at constant volume, 14.3.3 Absolute zero and the kelvin scale, 14.3.4 Compressing and expanding gases, 14.3.5 Volume and pressure at constant temperature, and 14.3.6 Doing work on a gas.
