Neco Model Questions Vol1 2021 Physics Question 16
Practice objective / multiple choice question 16 from the 2021 Neco Model Questions Vol1 Physics examination.
A sealed rigid container initially holds \(0.500\ \text{mol}\) of an ideal gas at a pressure of \(2.00\ \text{atm}\) and a temperature of \(300\ \text{K}\). The container is heated to \(450\ \text{K}\). To keep the pressure from exceeding \(2.00\ \text{atm}\), a valve is opened and gas escapes until the pressure stabilises at exactly \(2.00\ \text{atm}\) while the temperature remains at \(450\ \text{K}\). Assuming the volume of the container does not change, how many moles of gas escaped?
