Neco Model Questions Vol1 2017 Physics Question 20
Practice objective / multiple choice question 20 from the 2017 Neco Model Questions Vol1 Physics examination.
A sample of ideal gas occupies a cylinder with a movable piston. Initially the gas is at \(20^{\circ}\text{C}\) and a pressure of \(100\;\text{kPa}\). The gas is first compressed isothermally until its volume is reduced to one‑half of the original volume. Then, while the volume is kept constant, the gas is heated until its temperature reaches \(80^{\circ}\text{C}\). What is the final pressure of the gas in kilopascals? Give your answer to one decimal place.
