Demonstration 2: 50 grams of aluminom is added to 100 grams of water. The aluminem and the water are both initially at room temperature in a perfectly insulated cup. Heat energy is transferred to the system at the same steady rate as in the previous demonstration for 80 seconds, and then no more heat energy is transferred. (Note that the specific heat of water is 4186J/kg C and the specific heat of aluminum is 900 J/kg C.) Do you think that the change in temperature of the water plus aluminum will be greater than, less than or equal to the change in temperature in the previous demonstration? Only after you have made your predictions, click here to download and view a video of the experiment. Then, click here to view the starting and final temperatures. Compare the results to your predictions and explain any differences. Why is the temperature change smaller than in Demonstration 17 Record Temperatures Below: Starting Temperature: Ending Temperature: Change in Temperature: Calculation 2: Using the actual starting and ending temperatures of the system, determine the amount of heat that was transferred to the water and aluminum in this process. The specific heat of water is 4186J/kg C and the specific heat of aluminum is 900 J/kg CM Heat Transferred Q2= Only after you have made your calculation, click here to compare it.
