Gce Model Questions Vol1 2021 Mathematics Question 20
Practice objective / multiple choice question 20 from the 2021 Gce Model Questions Vol1 Mathematics examination.
For a certain gas the pressure \(P\) (in kPa) and volume \(V\) (in L) are related by \(P = k V^{n}\), where \(k\) and \(n\) are constants. Experimental data give \(P=150\) kPa when \(V=2\) L and \(P=60\) kPa when \(V=5\) L. Determine the exponent \(n\) and the constant \(k\). Then predict the pressure when the volume is \(3\) L. Give your final answer for the pressure to the nearest kilopascal.
