Question

Transferring Energy
A. How much energy would a jeweler need to melt4.4 grams of copper to fix a broken necklace if the copper starts out at 25°C and melts at 1083°C?
Please help, this is for a Chemistry final exam. I need at least a formula, and I can solve from there, I just can't seem to find it in my notes. Thanks in advance!

Answer 1

Use: \(\sf q = \color{red}{mC ~\Delta T}\)

where m = mass, C is the heat capacity, and \(\Delta\)T = change in temperature.
You just need the heat capacity of copper @ some fixed boundry. You can find that in your book or online.

Answer 2

Thank you once again :)
