Problem

A lab group is instructed to find the specific heat of copper. They are provided with a coffee-cup calorimeter, distilled water, and 50.0 grams of copper shot.
A photograph of copper shot, which are just tiny balls of copper metal.
Copper shot, ready for experimentation!
The calorimeter is filled with 200.0 grams of water at 22.9°C. The group heats the copper to 99.8°C, then pours the copper into the calorimeter. The final temperature of the system peaks at 24.6°C.
This problem requires multiple steps. Check your first steps here! (not scored)
