Neco Model Questions Vol1 2018 Physics Question 39
Practice objective / multiple choice question 39 from the 2018 Neco Model Questions Vol1 Physics examination.
A sealed cylinder contains an ideal gas at an initial pressure of \(2.0\ \text{atm}\), temperature \(300\ \text{K}\) and fixed volume \(5.0\ \text{L}\). The gas is heated to \(450\ \text{K}\) while the pressure is maintained at \(2.0\ \text{atm}\) by allowing gas to escape through a valve. (i) Determine the amount of gas (in moles) that escapes during the heating. (ii) After the valve is closed, the remaining gas is compressed isothermally at \(450\ \text{K}\) to a volume of \(2.5\ \text{L}\). Find the final pressure of the gas (in atm).
