Two aircraft rivets, one of iron and the other of copper, are placed in a calorimeter that has an initial temperature of 20.°C. The data for the metals are as follows:
Iron Copper
Mass (g)
30.0 20.0
Initial T (°C)
0.0 100.0
c (J/g·K)
0.450 0.387
Determine the maximum final temperature of the system (assuming the heat capacity of the calorimeter is negligible)?
