this water down to below room temperature, we added a little ice. After that we weighed the inner cup and stirrer together. After stirring gently and allowing calorimeter, water and ice to reach a constant stable temperature, we put the calorimeter near the steam chest and quickly transferred the specimen into the calorimeter. Lastly, we stirred the water in the calorimeter gently and recorded the temperature once final steady state temperature was reached. With all the data collected, we were able to calculate the heat gained by the calorimeter inner cup, water and stirrer, to find the specific heat of the specimen by applying the second equation. The steps were followed to find the specific heat of the copper specimen. Results These were the measurement that we got after performing the experiment for both specimens. Aluminum Specimen Mass of AL specimen (g) Mass of calorimeter inner cup and stirrer (g) Mass of calorimeter inner cup, stirrer, and water (g) Mass of water (g) Initial temperatur e of water ( ) Initial temperatur e of AL specimen ( ) Final temperatur e ( ) 85.4 g 82.5 g 292.1 g 209.6 g (292.1-82.25) 21.5 100 27.2

Copper Specimen Mass of AL specimen (g) Mass of calorimeter inner cup and stirrer (g) Mass of calorimeter inner cup, stirrer, and water (g) Mass of water (g) Initial temperatur e of water ( ) Initial temperatur e of AL specimen ( ) Final temperatur e ( ) 279.3 g 82.5 g 291 g 208.5 g (291-82.5) 26.8 100 30.5 With information, we were able to find the specific heat for both copper and aluminum specimen. The calorimeter inner cup was made out of aluminum and therefore, when we were trying to find the specific heat for aluminum, we knew that the specific heat for the inner cup and the specimen would be the same. We found our specific heat for aluminum to be .208 cal/g .

For the copper specimen, we found our specific heat to be .066 cal/g
