A pneumatic cylinder in an automated manufacturing robotic arm seals a volume of air to act as a gas spring, as shown in the diagram below.
Initial measurements of the sealed cylinder are:
- pressure (p1)=1.4×105 Pa\text{pressure } (p_1) = 1.4 \times 10^5 \text{ Pa}pressure (p1)=1.4×105 Pa
- volume (V1)=45.0 cm3\text{volume } (V_1) = 45.0 \text{ cm}^3volume (V1)=45.0 cm3
Calculate the volume of the gas,
V2 V_2 V2, when the piston is compressed slowly so that the pressure increases to
3.5×105 Pa 3.5 \times 10^5 \text{ Pa} 3.5×105 Pa, assuming the temperature remains constant.
Explain why compressing the piston very quickly would cause the temperature of the gas to increase.
Particle model and pressure Questions
Practise AQA GCSE Physics Particle model and pressure with exam-style questions for Foundation and Higher tier. 12 questions covering Particle motion in gases, Pressure in gases (physics only), and Increasing the pressure of a gas (physics only) (HT only), matched to the AQA GCSE Physics (8463) specification and written in Paper 1 and Paper 2 style. Every question includes a full worked solution and mark scheme, so you can see where marks are awarded rather than just whether you got the answer right.
