Question

Calorimetry

A 100g sample of hot copper is placed in a coffee cup calorimeter containing 100 grams of water at room temperature. After some time the temperature of the water and the copper become a constant at 50˚C. Calculate the initial temperature of the copper piece. The specific heat of copper is 0.385 J/g˚C. The specific heat of liquid water is 4.184 J/g˚C.
