Problem

A copper rod of length

0.50\,\text{m}

and cross-sectional area

8\,\text{cm}^2

has its ends maintained at

100^{\circ}\text{C}

and

0^{\circ}\text{C}

. If the thermal conductivity of copper is

385\,\text{W}\,\text{m}^{-1}\,\text{K}^{-1}

, calculate the steady heat current through the rod. a)
