(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

One end of an insulated metal rod is maintained at 100^\circ C and the other end is maintained at 0.00 ^\circ {\rm C} by an ice–water mixture. The rod has a length of 75.0 cm and a cross-sectional area of 1.40 cm^2. The heat conducted by the rod melts a mass of 7.85 g of ice in a time of 15.0 min. Find the thermal conductivity k of the metal.

2. Relevant equations

H=dQ/dt=kA(T_{2}-T_{1})/L

3. The attempt at a solution

I tried to solve for k using the formula for heat transfer and since H was not given, I substituted it withdQ/dt. Then in stead ofdQ I used the equation for heat transformation Q=mL where m=mass of ice melted and L=333kj/kg which is the heat of fusion for water, if I'm not mistaken. I put everything in SI units and solved but I got the wrong answer. Did I make a wrong assumption somewhere?
