Neco Model Questions Vol1 2017 Physics Question 23
Practice objective / multiple choice question 23 from the 2017 Neco Model Questions Vol1 Physics examination.
A vertical cylindrical container of cross‑sectional area \(A=0.020\,\text{m}^2\) contains air at atmospheric pressure \(P_{\text{atm}}=1.0\times10^{5}\,\text{Pa}\) and temperature \(300\,\text{K}\). The initial volume of the gas is \(V_i=4.0\times10^{-3}\,\text{m}^3\). A frictionless piston of mass \(5.0\,\text{kg}\) rests on the gas, with atmospheric pressure acting on the top of the piston. An additional mass \(M\) (in kilograms) is placed on top of the piston, compressing the gas until the gas volume becomes \(V_f=3.0\times10^{-3}\,\text{m}^3\). Assuming the compression is isothermal, determine the value of \(M\) required to achieve this final volume.
