A 1.0 102 g piece of copper at a temperature of 460 K and a 2.0 102 g piece of aluminum at a temperature of 2.2 102 K are dropped into an insulated bucket containing 5.0 102 g of water at 280 K. What is the equilibrium temperature of the mixture? (Use the specific heats found in this table.)


I have 252.2tf=57692
tf=228 K

Based off of the table the specific heats for Aluminum and Copper are. Al-0.900 and Copper-0.215
