Another fact, the iron hardness, is it bad that it did not quite taken strictly not true. Hardness

Iron is a medium-heavy material. The substance, in turn, is something which has mass - something which Theodore Gray's definition could knock on his toes (Gray 2009). Mass, in turn, is the energy in a compact form. (E = mc 2, you know?)
One of the natural law of the disorder, or entropy of the universe is growing all the time. Entropiaperiaate is also convenient for the amount of time direction, the order will be reduced and the random noise increases as the time goes by. No one, however no idea that how the universe was born in the original order, which over time will unravel.
Disorder of growth, this implies that the substance has a tendency to degrade radiation. Originally concise f&p and packed in good order, after having become the material comes into the radiation to escape the winds of space in disarray.
The material disperses the radiation on the condition that it somehow f&p succeeds. Before the material energy can be released from the radiation, it may have to overcome many threshold reactions, which do not release energy but on the contrary it is something outside more.
When the heavy elements are broken down, the result is a lighter elements, which are altogether a bit lighter than the original material. Mass has been lost. On the other hand when the light elements combine, the result is a heavier element, but not quite as heavy as the original ingredients together. The pulp is gone again.
But to return to the iron. Can you guess which element is light and heavy materials in the mid? The material from which the lamp should not be splitting the white stars on the one hand and the momentum by combining with other materials?
The universe is moving toward an all-time iron through. Heavy-duty materials break down and light combine until all the substance is changed f&p into iron. As Raimo on-one time put it, the basics of modern physics lecture: "Few of us now is iron, but in the future everything - and nothing will ever rust, because there is no longer f&p any oxygen. "
I have to mention f&p here in Malta again that same lecture series ending sentences, they are better when you can not really put: "That was the story of the universe. Is the universe any questions? "
Iron, and all the other heavy elements, the scale of the universe is only a tiny organic matters trivial compared to the lighter elemental form hydrogen and helium. Tähtitietelijöillä is a charming way to invite all the elements other than hydrogen and helium "metals".
Just some places there can be plenty of iron. For example, the earth is six thousand trillion f&p tonnes ainehippunen a big part of the core is iron. Continue to be the world's iron crib is one of the most common elements.
Another fact, the iron hardness, is it bad that it did not quite taken strictly not true. Hardness is a relative term, of course, but pure iron is quite soft metal. Alumiinikin is harder than iron.
Experience f&p working f&p familiar with the hardness of iron is due to the fact that iron is usually not pure, but mixed with carbon. The carbon makes the iron harder, but at the same time more difficult malleable. Ovelilla practical portfolio page can be adjusted to the amount of iron, carbon and oxidized carbon and other impurities in the iron so that the iron occurs steel.
The third fact, the rusting of iron, it is quite true, but the rust itself is not a problem. The problem f&p is that the rusted iron requires more space than stainless steel. Therefore, a rusty iron surface of an object flaking off and is revealed every time a new layer of iron corrosion f&p by exposure to it. Many other metals such as iron rust or oxidise easily, but their surface is oxidized haperru, but remains in the protective layer to the underlying metal.
Iron, oxygen can improve the sustainability of mixing it with other metals. Stainless steel is obtained by adding plenty of chrome steel. If you want to build a steel submarine, for example, you might want to add molybdenum. Other metals iron features can still tweak more.
The fourth fact, sticking to the magnet iron is a sensitive topic. I do not know how to explain magnetism. The problem f&p is the same as earlier in this story, as would have to explain why the disintegration of atomic nuclei and the combinations are released energy. Limits to quantum physics and quantum physics, in turn, is too strange to understand. However, the magnetism of iron gets out of heating: 770 C for rautamötikkään no longer sticks to the magnet, the AHA!
Raimo-person lecture, which I learned that iron is the most stable f&p element was held before 1995. Until then, "generally known" that the iron isotope 56 is the lowest binding energy of all the elements. Then the MP Fewell (1995) came to have found that it is not so: physics textbooks and encyclopaedias had only lived in the wrong information. A second isotope of iron, iron-58, respectively, is marginally lower si
