Neco Model Questions Vol1 2020 Physics Question 12
Practice objective / multiple choice question 12 from the 2020 Neco Model Questions Vol1 Physics examination.
A sealed gas occupies a cylinder of volume \(500\,\text{cm}^3\) at a temperature of \(27\,^{\circ}\text{C}\) and an unknown pressure \(P_{1}\). The gas is heated to \(127\,^{\circ}\text{C}\), causing the piston to move so that the volume increases by 20\% of its original volume. The final pressure is measured to be \(1.2\,\text{atm}\). Calculate the initial pressure \(P_{1}\) in atmospheres.
