Answer
Explanation:
Step1: Recall heat - flow principle
Heat flows from higher - temperature object to lower - temperature object.
Step2: Analyze Scenario A
Skin ($37^{\circ}C$) is at a higher temperature than lotion ($27^{\circ}C$), so heat flows toward object 1 (lotion).
Step3: Analyze Scenario B
Lasagna ($170^{\circ}C$) is at a higher temperature than the plate ($20^{\circ}C$), so heat flows toward object 2 (plate).
Step4: Analyze Scenario C
Lava ($950^{\circ}C$) is at a much higher temperature than ocean water ($25^{\circ}C$), so heat flows toward object 1 (ocean water).
Step5: Analyze Scenario D
Sidewalk ($80^{\circ}C$) is at a higher temperature than eggs ($2^{\circ}C$), so heat flows toward object 1 (eggs).
Answer:
Scenario A: toward object 1 Scenario B: toward object 2 Scenario C: toward object 1 Scenario D: toward object 1
