1) At the start, which calorimeter had the most potential energy?
-The Hot cup and the most potential energy.

2) Which calorimeter lost energy?
-The hot cup lost energy.

3) Which calorimeter was a heat source?
-The Hot cup was the h

4) In which direction did the heat energy flow?
-It is flowing from the hot cup to the cold cup

5) Compare the amount of energy lost by one cup to the amount of energy gained by the other cup.
-As the hot cup lost energy, the cold cup gained energy.

6) Explain the difference between the amount of energy lost by one cup and the amount of energy gained by another.
-Since hot always goes to cold, the hot cups energy is going to the cold cup. This is causing the colder cup to gain more energy and the hotter cup to loose more energy.

7) How does your graph show that there is a change in the rate if the heat lost or gained as time passed?
-The slope of the graph isn’t consistent. This indicated a change in the rate of heat lost or gained.

8) How does the rate if heat loss from the hot cup change during the experiment?
-The rate of heat lost by the hot water decreased. The slope decreased.

9) If the experiment were left standing for 24 hr, what predictions could you make about the temperature of the cups.
-I predict that the temperature of the cups would be around the same temperature.

10) How could you modify the experiment to increase the rate of heat transfer from the hot cup to the cold cup?
-In the experiment the metal bar was used to transfer hear. To speed up the process of heat transfer you can use a better conductor to transfer the heat faster.

11) Explain why there is a change in rate of energy exchange as time passes.

Conclusion: Explain how heat is transferred from the water in one calorimeter to the water of the other calorimeter.
-The heat from one cup to another is done so by means of a conductor (the metal bar).
