2. The cold water gradually turned warmer. This was because it was heated by the hot water.
3. Since the warm water was heating the cold water it lost some of its heat resulting in almost equal temperatures.
4. Our graph showed how the temperatures gradually merged to about the same temperature.
5. At about fifteen minutes the temperatures were only a few degrees away from each other. The temperatures were between 54 and 50.
6. The heat from the hot water warmed the cup and that warmed the cold water. Now the cold and hot water are the same temperature.
7. The hot water warmed up the cold water so it lost some of its heat to the cold water. Resulting in the temperature being close to the same.
8. It would probably be a few degrees warmer for the cold and colder for the hot water. We chose this because we looked at from ten to twenty minutes and there were two degrees in between them. We thought it would be the same from thirty to forty.
9. The water did not go through the red solo cup. The food coloring in the hot cup did not show up in the cold water. Yes the food coloring help us figure out that the water didn't go through the cup.
