Why did you use two coffee cups during the experiment instead of just one cup?
A-in case a hole was punctured in the inside cup
B-to add more weight in order to stabilize the calorimeter
C-to hold all of the water in the experiment
D-so that the water temperature would not change at all during the experiment
E-to prevent heat from escaping from the calorimeter
the correct answer is E i just got this one right.
