Neco Model Questions Vol1 2023 Physics Question 7
Practice essay / theory question 7 from the 2023 Neco Model Questions Vol1 Physics examination. This question covers Pressure .
A vertical cylindrical container of cross‑sectional area 0.020 m² is closed at the bottom and fitted with a frictionless movable piston at the top. Initially the piston is held so that the gas inside occupies a volume of 0.040 m³ at a temperature of 300 K and a pressure equal to atmospheric pressure (1.00×10⁵ Pa). The surrounding air temperature remains constant at 300 K and the external atmospheric pressure is 1.00×10⁵ Pa. The piston is then released and the gas expands until the pressure inside again equals the external atmospheric pressure. Afterwards the temperature of the gas is raised while the piston is kept fixed, and finally the whole apparatus is placed underwater.
