Can anybody tell me what happens to iron when heated and iron's main properties and uses !?
Whe iron is heated to 1535 C, it melts. It's principal use is in making steel. It is also an important mineral needed (in small amounts) in human diets, because it is present in red blood cells.
Before iron melts while being heated, it becomes more malleable.
However, since this is not my area of expertise, I searched Google under the key words "iron properties uses" to get these possible sources:

I hope this helps a little more. Thanksfor asking.
When iron is heated, it undergoes various changes based on the temperature. At room temperature, iron is solid and has a silvery-gray appearance. As the temperature increases, iron starts to expand and becomes more malleable, meaning it can be easily shaped or bent without breaking. This property is useful in various applications, such as blacksmithing and metalworking.
As the temperature continues to rise, iron undergoes a phase change and begins to melt. This occurs at a specific temperature known as the melting point, which for iron is approximately 1535 degrees Celsius (2795 degrees Fahrenheit). When iron is heated to this temperature, it becomes a liquid and can be poured into molds to form different shapes.
Iron's main property is its ability to form alloys, particularly steel. Steel is an alloy made primarily from iron with small amounts of carbon and other elements. This makes steel stronger, more durable, and resistant to corrosion, making it suitable for a wide range of applications such as construction, manufacturing of tools and machinery, transportation, and infrastructure.
Iron also has important biological significance. It is a vital mineral required in small amounts for human health. Iron is a critical component of hemoglobin, a protein found in red blood cells that transports oxygen from the lungs to the rest of the body. Iron deficiency can lead to health problems like anemia.
To find this information, I recommend conducting a search on a search engine like Google using keywords such as "iron properties" or "uses of iron." This will provide you with a variety of sources, including scientific websites, educational resources, and research papers, where you can find in-depth information about iron's properties and uses.
