What else can I help you with?
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.
How many different kinds of metal can electromagnetism pick up and at what voltage?
Certain materials are strongly magnetic, such as nickel, iron, cobalt, and their alloys. Whether or not a particular electromagnet can pick up a particular piece of metal (assuming it in one of those on the list) depends on the size and weight of the metal and the strength of the electromagnet. http://en.wikipedia.org/wiki/Magnetism
What is the process called when removing impurities from Iron Ore?
The process is called smelting. It involves heating the iron ore in a furnace with a reducing agent such as coke (carbon) to remove the impurities and extract the pure iron metal.
Is pig iron non ferrous metal?
No, pig iron is not a non-ferrous metal. Pig iron is a type of iron produced by smelting iron ore in a blast furnace. It contains a significant amount of carbon and other impurities, making it distinct from non-ferrous metals which do not contain iron.
What gas removes impurities in pig iron?
The gas that is commonly used to remove impurities in pig iron is carbon monoxide. It reacts with the impurities in the iron, such as oxygen and sulfur, to form less reactive compounds that can be easily separated.
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.
How can thermometer be used to check the purity of a metal such as gold or iron?
A thermometer can be used to test the purity of a metal by measuring its specific heat capacity. Different metals have different specific heat capacities, so comparing the measured value to the known values for pure gold or iron can indicate the level of impurities present in the sample. A lower specific heat capacity than the known value may indicate impurities in the metal.
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.
How is iron ore processed to extract the valuable metal?
Iron ore is processed through a series of steps to extract the valuable metal. First, the ore is crushed and ground into small pieces. Then, it is concentrated using magnetic separation or flotation to separate the iron from other minerals. Finally, the iron is smelted in a furnace to remove impurities and obtain the pure metal.
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
What property does iron have the ability to rust?
Iron has the ability to rust due to a chemical reaction with oxygen and water in the presence of impurities like salts. This reaction forms iron oxide (rust) on the surface of the iron, which weakens the metal over time.
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 impurities are present in iron ore?
Common impurities found in iron ore include silica, alumina, phosphorus, and sulfur. These impurities can affect the quality of the iron produced during the smelting process and need to be minimized through various beneficiation techniques.
Why is cast iron more brittle than mild iron?
Brittle because it contains impurities such as carbon and sulfur. The structure of the molecules in iron, particularly when cast, is such that it is almost crystalline in nature and breaks easily. The addition of carbon and other metals into the mix gives you more malleable compounds that are less brittle and can convert it to what we refer to as steel.
