Neco 2021 Physics Question 8
Practice essay / theory question 8 from the 2021 Neco Physics examination. This question covers Heat, Thermal conductivity, Fourier's law, Steady‑state heat transfer .
A uniform metal rod of length \(L=1.20\,\text{m}\) and cross‑sectional area \(A=2.0\times10^{-4}\,\text{m}^{2}\) is made of an alloy whose thermal conductivity is to be determined. One end of the rod is maintained at \(150^{\circ}\text{C}\) while the other end is kept at \(30^{\circ}\text{C}\). Under steady‑state conditions the rate of heat flow through the rod is \(45\,\text{W}\).
