Answer
Explanation:
Step1: Recall heat - flow principle
Heat always flows from a hotter object to a colder object.
Step2: Analyze Example 1
Fire is hotter than air, so heat flows from Object 1 (fire) to Object 2 (air).
Step3: Analyze Example 2
The metal at 80°C is hotter than the metal at 12°C, so heat flows from Object 1 (80°C metal) to Object 2 (12°C metal).
Step4: Analyze Example 3
The warm air is hotter than the cool ocean, so heat flows from Object 2 (warm air) to Object 1 (cool ocean).
Step5: Analyze Example 4
The tool with a lot of thermal energy is hotter than the material with little thermal energy, so heat flows from Object 1 (tool) to Object 2 (material).
Answer:
Heat will flow from Object 1 to Object 2 in examples 1, 2, and 4, and heat will flow from Object 2 to Object 1 in Example 3.
