1. Look up the specific heat of copper. Call it C. Look for or compute its value with units of cal/(g*C) . You may find published values of C with different units, with kg or Joules.

The heat absorbed is
Q = M C*(delta T)
where delta T is the change in temperature, which is 5.0 C in this case. M is the mass in grams.
