A scientist is attempting to determine the specific heat of a new alloy of mass 0.12 kg. It is heated to 100 °C, then placed in a brass calorimeter. The mass of the calorimeter is 0.5 kg at an initial temperature of 34 °C. The calorimeter contains water of mass 0.25 kg at the same temperature. The equilibrium temperature of 75 °C is reached. Write an equation to describe the transfer of energy, using Q = mcAT. a. b. Write the equation with the speçific heat capacity of the alloy as the subject of the formula. Given that the specific heat.capacity of water is 4.19 x 103 J/kg°C and the с. calorimeter has a specific heat capacity of brass is 380 J/kg°C. What is the specific heat capacity of the alloy?
