Neco 2021 Physics Question 17
Practice objective / multiple choice question 17 from the 2021 Neco Physics examination.
A sealed \(2.00\,\text{L}\) container initially contains an ideal gas at \(1.00\,\text{atm}\) and \(27^{\circ}\text{C}\). The gas is heated at constant volume until the pressure rises to \(2.50\,\text{atm}\). It then expands isothermally at the final temperature until the pressure returns to \(1.00\,\text{atm}\). (a) Find the final volume of the gas after the isothermal expansion. (b) If the gas is monatomic with molar heat capacity at constant volume \(C_{V}=\tfrac{3}{2}R\), calculate the heat added during the constant‑volume heating step. Give your answer in joules to three significant figures.
