Question text not available

Mass of copper: g

Mass of iron: g

Mass of lead: g

(metal) = – °C

Mass of aluminum: g

Tare the balance. Put calorimeter (no lid) on the balance. Measure the mass to the nearest 0.01 g. g

Initial temperature of metal = °C

Tare the balance. Put calorimeter (no lid) on the balance. Measure the mass to the nearest 0.01 g. g

Use a graduated cylinder to add approximately 40 mL of water to the calorimeter. Measure the mass of the calorimeter (no lid) and water to the nearest 0.01 g. g

Initial temperature of metal = °C

Subtract to find the temperature changes for the water and the metal. (water) = °C

Initial temperature of metal = °C

Use your data, the equation to the right, and the specific heat of water (4.184 J/g°C) to compute the specific heat values of each metal. Use a calculator and round to the nearest hundredth place.Aluminum: c = J/g°C

Lead: c = J/g°C
