Problem

One end of a copper rod of length

1\ \text{m}

and cross-sectional area

4.0\times10^{-4}\ \text{m}^2

is maintained at

100^\circ\text{C}

. At the other end of the rod, ice is kept at

0^\circ\text{C}

. Neglecting heat loss to the surroundings, find the mass of ice melted in

1\ \text{h}

. Given

k_{\text{Cu}}=401\ \text{W m}^{-1}\text{K}^{-1}

and

L_f=3.35\times10^5\ \text{J kg}^{-1}
