Gce Model Questions Vol1 2022 Physics Question 26
Practice objective / multiple choice question 26 from the 2022 Gce Model Questions Vol1 Physics examination.
A vertical column of oil of unknown height h rests on a frictionless piston. The gas beneath the piston exerts a pressure of \(1.20\times10^{5}\,\text{Pa}\) at a temperature of \(300\ \text{K}\). Atmospheric pressure is \(1.00\times10^{5}\,\text{Pa}\). The oil has a density of \(900\ \text{kg m}^{-3}\) at \(300\ \text{K}\) and its density varies with temperature as \(\rho = \rho_{0}\bigl[1-\alpha (T-300)\bigr]\) where \(\alpha = 2.0\times10^{-4}\ \text{K}^{-1}\). The oil temperature is \(350\ \text{K}\). Determine the height h of the oil column (in metres).
