• Energy = mCp(T2-T1) so answer is negative for energy lost (final temp lower) m = mass (kg) Cp = Heat capacity (J/kgC) T2 = final temp T1 = Initial temp Energy lost by metal = energy gained by water. So: Water (mCp(T2-T1)) = Metal (mCp(T2-T1)) YOu have all values except Cp of the metal so just plug them in and your done! :)
