A 100g aluminium calorimeter contains 250g of water. The two substances are in thermal equilibrium at 10°C. Two metallic blocks are placed in the water. One is a 50g piece of copper at 80°C, and the other sample has a mass of 70g and is originally at a temperature of 100°C. The entire system stabilizes at a final temperature of 20°C. Determine the specific heat capacity of the unknown second sample [Cualuminium=900Jkg-1K-1, Cwater=4186Jkg-1K-1, Cucupper=387Jkg-1K-1]
