Neco Model Questions Vol1 2018 Physics Question 46
Practice objective / multiple choice question 46 from the 2018 Neco Model Questions Vol1 Physics examination.
A sealed cylinder contains an ideal gas at a pressure of \(2.0\ \text{atm}\) and a temperature of \(300\ \text{K}\), occupying a volume of \(4.0\ \text{L}\). (i) The gas is heated at constant volume until its temperature reaches \(450\ \text{K}\). (ii) It then expands isothermally at this temperature until the pressure falls back to \(2.0\ \text{atm}\). Calculate the total work done by the gas during the isothermal expansion stage. Give your answer in joules (J) to three significant figures.
