Answer
Explanation:
Step1: Recall heat - flow principle
Heat always flows from a higher - temperature or higher - thermal - energy object to a lower - temperature or lower - thermal - energy object.
Step2: Analyze Example 1
Fire is at a high temperature. Air is at a lower temperature. So heat flows from Object 1 (Fire) to Object 2 (Air).
Step3: Analyze Example 2
The metal at 80°C is at a higher temperature than the metal at 12°C. So heat flows from Object 1 (the 80°C metal) to Object 2 (the 12°C metal).
Step4: Analyze Example 3
The warm air is at a higher temperature 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 has a higher thermal - energy state 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.
