Àn aluminum (specific heat capacity = 0.90 Jig-*Č) calorimeter of mass 100 g contains 251 g of water (specific heat capacity = 4.184 J/g-*C). The calorimeter and water are in thermal equilibrium at 10°č. Two metallic blocks are placed in the water. Öne is a 50 g piece of copper (specific heat = 0.386 J/g-"C) at 80°C. The other has the mass of 66 g and is originally at a temperature of 100°C. The entire system stabilizes at a final temperature of 20°C. What is the specific heat capacity of the unknown metallic block in Jig-"C?
