A block of iron (Fe) of mass mre = 0.200 kg at Tre,i=85.0 C and a block of aluminum (Al) of mass mal at TAL = 5.0 C are brought into direct physical contact inside an insulated chamber. After a long time, the metal blocks reach thermal equilibrium at a temperature Ty= 20.0 C. CFe =0.107 cal/gC CAI 0.215 cal/gC a. List all relevant heat transfers and indicate which are positive and negative b. Write a symbolic expression for the calorimetry equation ;Q=0 in terms of the quantities defined in the problem. c. Calculate the mass of block of aluminum: A block of iron (Fe) of mass mre = 0.200 kg at Tre,i=85.0 C and a block of aluminum (Al) of mass mal at TAL = 5.0 C are brought into direct physical contact inside an insulated chamber.
