Oxygen And What Element Is Oxygen
What Is Oxygen - sometime we read news about an event in which people "suffocation". well, there's one thing from him can we pull the conclusion that human beings cannot live without oxygen. without inhaling the substance oxygen that humans are unlikely to live more than a few minutes.
What Element Is Oxygen
oxygen is an element, even the most abundant element, which is contained in our nature. nearly half of the layer of the Earth's crust is covered by oxygen, while the rest of not less than one-fifth of our air that contains oxygen.
the oxygen that we breathe substances enter into our lungs, oxygen carried by the red blood cells through a channel that is fixed to the all corners of the tissue cell of our body. oxygen combustion process pushing against our food substances, producing heat that we need to maintain the continuation of the activities of the organs of the human body.
oxygen can be easily combined with almost all items, when it takes place, then the process that we call "oxidation". when this process of oxidation occurs very quickly, then we experience is "combustion" or burning.
almost in all the oxidation process that there was heat emitted. in the process of combustion heat issued so quickly, so there is no time anymore for had wasted away. the temperature of the height, and flames appear.
so, on the one hand we are dealing with combustion, i.e. the oxidation process which is fast paced and produce a flame, while on the other hand we are experiencing this type of oxidation burning food substances in our body and maintain the continuity of the process of the activities of our lives.
but a slow oxidation process, which is performed by oxidation in air, there is also everywhere. when we see iron rusting, paint the walls that used to wet into dry. drink alcohol turns into vinegar, then this means it has happened an oxidation.
the air we breath is actually the main mixture between nitrogen and oxygen. so, we can obtain pure oxygen from the air. the trick is to cool the air to a temperature so low so it turns into a liquid, the temperature required is more than 300 degrees below zero Fahrenheit.
so that liquid is heated above the temperature returns above, then the water will boil. and in boiling water come out first are substances of nitrogen, while the substance oxygen remained in it.
people have had many lives saved by providing supplies oxygen to them so that they can breathe easily and relieved, when their lungs started to noticeably weakened.
