Energy - Lesson 4: Transferring Heat Energy from Warm to Cold Water

questions

​

1. How did the temperatures of the water in the two red Solo cups compare at the beginning?
2. What happened to the temperature of the cold water over time?
3. What happened to the temperature of the warm water over time?
4. How did your graph show what happened?
5. After 15 minutes, what did you notice about the lines on your graph?
6. What happened to make the temperature of the cold water get warmer?
7. What happened to make the temperature of the warm water get colder?
​
8. Use your line graph to predict when the two lines would merge. Describe. Why did you choose this timeframe?
​
9. Which direction did the heat energy move?

Answers

1.In the cup that had cold water it started rising and I thought that the cold water was going to stay the same but it did not and it's temperature changed.  
2.The temperature in the the cold water really changed over time and the water got hotter and it really surprised me. 
3.The hot water over time started to cool down like normal and it really changed it temperature over the time of our experiment.
4.The graph showed what the temperature of that cup of water was at that time and it showed how the hot and cold water was moving up and down on the graph. 
5.After the 15 minutes I saw that the cold water was at about 45 five degrees but I really don't remember. 
6.You know that cold water gets warmer right but you see the cold water was under light an dover time the light can heat the water up over the time of our experiment.
7.The warm water like always gets cool right but it cools down but some times when you leave it out for a really really long time it will cool down a lot like I mean a lot lot.
8.So, I think after 30 to 40 minutes I think the two lines will merge because of the temperature of the water over the time. 
9. The heated water moved down over time because it's temperature was going down when it was cooling during the whole experiment period.
