Question

A coffee cup calorimeter contains 100g water at an initial temperature of 20 degrees * C . A 10 g piece of unknown metal with a temperature of 100 degrees * C is placed into the calorimeter. The calorimeter comes to a final temperature of 35 degrees * C . What is the specific heat capacity of the metal? (The specific heat capacity of water is 4.18 J/g^ C . Please show your final answer with 3 significant figures)

Step 1

18 J/g^{\circ}C \times (35^{\circ}C - 20^{\circ}C)\) \(q_{water} = 100g \times 4.18 J/g^{\circ}C \times 15^{\circ}C\) \(q_{water} = 6270 J\) Show more…
