Students in a physics lab are to determine the specific heat of copper experimentally. They heat 0.150 kg of copper to 100oC and then transfer it into the calorimetry cup containing 0.200 kg of water at 20oC. The final temperature of the mixture in the cup is measured to be 25oC. If the aluminum cup (specific heat of 920 J/kg.Co) has a mass of 0.037 kg, what is the specific heat of copper?
