Problem

A glass pane is

0.008\,\text{m}

thick and has an area of

0.40\,\text{m}^2

. One surface is at

30^\circ\text{C}

and the other at

20^\circ\text{C}

. The thermal conductivity of glass is

k = 0.80\,\text{W}\,\text{m}^{-1}\,\text{K}^{-1}

. Calculate the steady-state rate at which energy is conducted through the pane.
