1. The problem statement, all variables and given/known data A 100.0 g copper sample (specific heat 0.385 J/g K) at 100 C is added to 50.0 g of water at 26.5 C. What is the final temperature of the copper-water mixture? 2. Relevant equations q = q(copper) + q(water) q = (heat capacity)(change in Temp.) q = (specific heat)(mass)(change in Temp.) 3. The attempt at a solution So far i have found the heat capacity of copper to be 0.385 J/K I know the metal loss of heat must equal the waters gain in heat but i do not know how to calculate the gain/loss.
