how will the rod start becoming after puting it into fire
Answers
Answer:
In the United States, the National Fire Protection Association (NFPA) does not currently endorse a device that can prevent or reduce lightning strikes.
Answer:
When we heat an iron rod, some amount of heat energy that was absorbed by iron rod is emitted as light. First iron turns into red (lower energy corresponding to higher wavelength) and as the temperature rises it glows and turns into orange, yellow, blue respectively (higher energy and lower wavelength). If we go on heating the rod it turns into white light which includes all visible wavelengths.
Explanation:
You might have observed that a frying pan becomes hot when kept on a flame. It is because the heat passes from the flame to the utensil. When the pan is removed from the fire, it slowly cools down. Why does it cool down? The heat is transferred from the pan to the surroundings. So you can understand that in both cases, the heat flows from a hotter object to a colder object. In fact, in all cases heat flows from a hotter object to a colder object.
