Neco 2022 Physics Question 7
Practice essay / theory question 7 from the 2022 Neco Physics examination. This question covers Pressure, Ideal gas law, Polytropic processes, Work done on a gas, Material strength .
A vertical piston-cylinder assembly contains 1.20 mol of an ideal gas at an initial pressure of 1.00 \times 10^5 Pa, a temperature of 300 K and a volume of 2.50 \times 10^{-2} \text{ m}^3. The piston is moved slowly so that the gas is compressed to a final volume of 1.80 \times 10^{-2} \text{ m}^3 while the temperature is raised uniformly to 420 K. The compression follows a polytropic process described by \(PV^{n}=\text{constant}\) with exponent \(n = 1.20\). The cylinder is made of steel whose ultimate tensile strength is 5.0 \times 10^8 \text{ Pa}.\
