Waec Model Questions Vol1 2019 Physics Question 30
Practice objective / multiple choice question 30 from the 2019 Waec Model Questions Vol1 Physics examination.
A rigid sealed container of volume 2.0 L initially contains 0.5 mol of an ideal gas at 300 K. A second ideal gas is then introduced, adding 0.2 mol at 350 K. The container is subsequently heated to 400 K. Assuming no gas escapes and the gases behave ideally, find the final pressure in the container in kilopascals (kPa). (R = 0.0821 L·atm·K⁻¹·mol⁻¹, 1 atm = 101.325 kPa.)
