Step 1

The heat lost by metal is equal to the heat gain by the water and calorimeter. The final temperature of water (Tf) is calculated using equation (1) in which Cw, CN, and Cc is the heat capacity of water, nickel, and calorimeter, respectively. mw and mN is the mass of water and nickel, respectively. ΔTN, &D...
