Waec Model Questions Vol1 2021 Physics Question 34
Practice objective / multiple choice question 34 from the 2021 Waec Model Questions Vol1 Physics examination.
A U‑tube manometer contains mercury (density 13 600 kg·m⁻³). One leg is open to the atmosphere (pressure 101.3 kPa). The other leg is connected to a sealed rigid container that holds an ideal gas at 300 K. Initially the mercury level in the gas‑connected leg is 0.106 m lower than the atmospheric leg. When the gas is heated to 350 K, the level difference increases to 0.250 m. Assuming the container volume does not change, determine the initial pressure of the gas (in kPa) at 300 K.
