Results: After the paperclip was placed near the aluminum foil, the petroleum jelly turned into liquid
Discussion:
1. What happens to the blobs of petroleum jelly when the end of the paper clip was placed near the electric burner?
- The blobs turned into liquid.
2. How is heat transferred from the heat source to the blobs of petroleum jelly?
- The heat is transferred by conduction. Specifically, the heat transferred from the electric burner, to the aluminum foil, to the paper clip, and then to the blobs.
Conclusion:
- Heat can be transferred by conduction through several media.
