A sheet of gold weighing 12.0 g and a temp of 28.0 C is placed on a sheet of copper weighing 34.0 g and a temp of 562 C. What is the final temp of the combined metals? Specific heats of gold and copper are 0.129 J/gC and 0.385 J/gC. No heat is lost to the surrounding. The heat gained by the gold must be equal to the heat lost by the copper. I can work the problem till I get to this: tf - 28.0 8.44 tf + 474. Now I‘m lost. Ant advice or help please? Thank you!!
