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. Δ*TN*, &D...
