scenario d toward object 2

Question

Accepted Answer

# Brief Explanations:
Heat flows from a region of higher temperature to a region of lower temperature.
- **Scenario A**: Skin ($37^{\circ}C$) is hotter than lotion ($27^{\circ}C$), so heat flows from object 2 (skin) to object 1 (lotion).
- **Scenario B**: Lasagna ($170^{\circ}C$) is hotter than plate ($20^{\circ}C$), so heat flows from object 1 (lasagna) to object 2 (plate).
- **Scenario C**: Lava ($950^{\circ}C$) is hotter than ocean water ($25^{\circ}C$), so heat flows from object 2 (lava) to object 1 (ocean water).
- **Scenario D**: Sidewalk ($80^{\circ}C$) is hotter than eggs ($2^{\circ}C$), so heat flows from object 2 (sidewalk) to object 1 (eggs).

# Answer:
Scenario A: toward object 1
Scenario B: toward object 2
Scenario C: toward object 1
Scenario D: toward object 1
