Metal impurities can have many different effects on iron. Some of these effects may include, but are not limited to differences in strength, chemical inertness, and flexibility.

How does a thermostat on an iron work?
it works by having the bimetallic strip coil turning away after the iron is heated to a certain temperature so the iron has a certain temp to reach and the thermostat would keep turning on and off so the temperature would still remain constant and therefore the iron can still be used even if left out for awhile.
Why would you use iron to replace power lines?
If Iron conducts eleticity long distances better than any other metal then that would be one reason.
Can electricity flow through iron gold?
I don't know what "iron gold" is, but electricity will flow through any metal pretty well.
What are some examples of insulators of electricity?
Wood, plastic, glass, --> holds electrons tightly. opposite of conductors.
What is the process of adding some impurities to semiconductor material?
Its called doping.
How a termometer can be used to check the purity of a metal?
because gold or iron are metal if they are not a metal so they can not check the purity but they are metals..
Why is iron a good metal for to use for bridges?
Iron as a metal in the pure form is somewhat fragile. But iron mixed with some impurities like Carbon is very strong which is used in the construction of bridges. This iron mixed with impurities is called as Cast Iron.
What is the method for purifying iron?
After iron ore is mined it is crushed into a powder then injected into a blast furnace. Under the extreme temperatures the ore melts and since iron is more dense than the impurities, it sinks to the bottom. This leaves a film of "slag" (impurities) on top. The slag is then skimmed off so only the metal remains.
What COLOR is gold and iron oxide?
Gold will be gold inside. Iron may vary some based on oxidation and the impurities mixed in with the metal, but is typically going to be 'rust' brown.
What metal did Henry Bessemer invent a cheaper way to make?
Steel. He figured out that if air was blown into the molten iron it would remove the particles that were impurities in the iron. This made steel.
What did Henry Bessemer add to iron to make steel.?
By blowing air through the molten pig iron. By adding oxygen to the iron it removed impurities which escape as gas or form a solid slag
When oxygen is blown into pure iron to remove impurities Wont it react with Iron itself to give iron oxide?
Oxygen is not blown into pure iron, it is blown into molten iron ore (many impurities) and coke has been added to the mix as well. the coke reacts with the impurities and the oxygen to purify the iron ore.
What gas removes impurities in pig iron?
Oxygen. When oxygen is forced through molted iron it reacts with the carbon, turning into carbon dioxide and bubbles away, leaving a cleaner metal behind.
What effects does oxygen have on metals?
Oxygen on metals may have many different effects depending on the metal and what the oxygen is combined with. Oxygen combined with moisture on the metal of steel or iron will cause the metal to rust.
Does an element of iron contain oxygen?
No. Fe- (latin) ferrum with the atomic number of 26.
How does calcium carbonate purify iron?
Calcium carbonate (limestone) is used in blast furnaces to capture impurities and form a slag that floats above the molten iron to keep the impurities from mixing back into the iron.
Is iron ore homogeneous?
no because it contains impurities
