Waec Model Questions Vol1 2021 Physics Question 7
Practice essay / theory question 7 from the 2021 Waec Model Questions Vol1 Physics examination. This question covers Pressure, Hydrostatics, Ideal gas law, Work done by fluids .
A vertical cylindrical tank of internal cross‑sectional area 0.50 m² has a total height of 10.0 m. The tank is closed at the top by a frictionless piston that initially locks the air inside at atmospheric pressure (101.3 kPa) and temperature 300 K. Water fills the lower part of the tank to a depth of 6.0 m. A valve at the bottom of the tank is opened, allowing water to flow out until the water level falls to 4.0 m, after which the valve is closed. The process is carried out slowly so that the trapped air behaves isothermally. Assume the density of water is 1000 kg·m⁻³ and the air behaves as an ideal gas. Answer the following:
