You computed the specific heat for each of the four metals using the formula below: Check all items that you used, either directly or indirectly, each time you did this computation.

Question illustration
A
the first law of thermodynamics (heat lost by a metal equals the heat gained by the water)
B
the ability of heat to flow from a hot object to a cooler one
C
masses for the metal and the water in the calorimeter
D
temperature changes for the water and the metal
E
the known specific heat of the water

Now you need to put handles on your cookware! You have five different options, including metals and nonmetals such as wood. Based on specific heat, which material would be the best choice?

A
the material with the smallest specific heat
B
the material with the greatest specific heat
C
the material whose specific heat is farthest from the specific heat of the metal pan
D
the material whose specific heat is closest to the specific heat of the metal pan

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
