Oxygen, and space what are the effects?

  1. Jan 10, 2012 #1
    Since space is a vacuum. And humans breathe out oxygen which will transform into carbon dioxide, would it transform(not really transform, you all know what my reference is)(what does it really do when it leaves our body?)into carbon dioxide and after it is sucked into spaces' vacuum, where does it go? if it stays at it's original form of oxygen, still where does it go. And why would it morph to carbon dioxide if it does? and how could the sun(since a gas substance) exist since it's a mix of Gases?

    Carbon dioxide is formed in the body, not upon exhalation. Your belief that it is formed after it leaves the body is incorrect.

    In short, oxygen is used to burn glucose producing ATP, which the body uses for energy. The byproducts of this process are water and CO2, both of which are expelled in exhalation.

    Inside your body the Oxygen molecule, which is two Oxygen atoms bound together in a molecule labled O2, is taken into your cells and through a process called cellular respiration it is converted into Carbon Dioxide (CO2) and Water (H2O). The carbon and Hydrogen come from the foods you eat. Your cells have little "factories" called mitochondria which is where this process takes place.

    the sun exists as a mix of gases because of the combined gravitational pull of all of those molecules of gas inside of it. There are so many molecules of gas that are so close together that gravity forces them together.

    If you look at the way a star forms, it might be easier to understand. Stars form through a process called accretion. What that is is a bunch of little tiny molecules of gas and dust and whatever else bumping into each other. Since each molecule has mass, it is attracted to other molecules of gas. When two attract to each other and remain stuck like that, they get a third, and a fourth, and so on until it becomes and appreciable ball of matter.

    This continues over a very looooong period of time. Also as a side effect of all the molecules and particles being attracted to it, the ball of matter starts to spin. As it spins and grows larger it begins to heat up. If enough mass accumulates, the ball of matter suddenly lights up. I think at this point it is called a protostar, though it might even be called that before this point. The protostar lights up because it is so hot and dense at its center that a certain kind of nuclear fusion has begun to take place and this produces even more energy and heat and thus photons. There are a few more levels of fusion as the protostar continues to get even bigger and hotter and denser until eventually it has the regular old hydrogen to helium fusion process going on inside of it.

    At this point you have something that probably looks like our Sun. Even though it is made of gases, the pressure due to gravity and also the heat in its inner layers means that these gases behave in odd ways.

    Don't take this all too literally and don't believe it 100% because it's just what I remember from watching TV shows about stars on the Discovery channel when I was younger.

    Yes, the accretion process generates heat as the gas collapses in on itself. Eventually the core of the protostar reaches such a high temperature that Nuclear Fusion starts taking place. During this whole process the star glows, with it's light output based on its temperature and size.

    Does the energy from the sun and others reach out to others suns, since time is unageable, and also goes on forever. Does the energy from the other suns of the universe ever interact on our sun? and when light from an energy source which is giving it off, it will give energy, is that energy contained inside of light it'self or is the energy and the light 2 different components in which create light, or is the energy what makes light?

    Could matter it'self has a relation to the attraction. Is that attraction gravity?

    How does the gravitational pull, grow on something as it gains more mass?

    If 2 stars form and go through the final stage processing and complete the process of formations at the literal exact same moment. synchronized. What is that phenonmenon be called? if it is? how is it a phenonmenon? and is there a relation between the stars if that were to occur?

    Energy is a quantity that is always transferred around and does nothing "on its own". IE that means that energy itself can't reach out and do anything. The energy released from the Sun is transferred through EM Radiation, aka light, and through neutrinos. When these interact with other particles, such as here on Earth, the energy is transferred to to the receiving particles. The light and neutrinos themselves have the energy and carry it away from their source. Energy is kind of complicated and confusing, and there have been several threads about it, so there isn't really an easy answer.

    So as long as the Sun is emitting radiation, it is giving off energy.

    Mass and energy create gravity. The standard thinking is that they warp spacetime, and the effect of this warping results in gravity. Since all matter has mass, all matter creates gravity and is affected by it.

    When you pack more mass into an area, the overall gravitational attraction grows. Also, when that same mass is packed into a smaller area the force is now greater within that new area because the same mass is concentrated more.

    There is no phenomena associated with this really, it's just coincidence. In reality even under this scenario the two stars would have minute differences that would make them different.

    If we are always losing energy, are we always gaining energy? What effects the energy and it's uses or transformations?
     
  14. Jan 16, 2012 #13
    We aren't always losing energy. There is a law saying that energy is never gained or lost in the entire universe, but this does not apply to single things. An object can lose energy, as long as something else gains the exact amount of energy that the first object lost.

    Can you be more specific? What do you mean by "We are always losing energy"?
     
  16. Jan 17, 2012 #15
    Since we are always using energy every second, could it be possible we are always gaining energy? could there be energy in other dimensions, what kind of dimension is the energy that is in our body? isn't it 1 dimensional? and also if you could can i have a link to a website that could help my thinking process. My thinking is been fuzzy for a little bit. and I would like a website or something that could guide my thinking. if you could?

    Energy isn't dimensional. We are constantly converting potential energy into different types of energy. For example, the sun is fusing hydrogen into helium and turning the mass into energy that gets released as light and neutrinos. The helium has LESS mass than the hydrogen atoms did before they fused, with the difference being released as energy. One would have to ADD energy to convert the helium back to hydrogen atoms. During this process both mass and energy are conserved. There is never any missing, only transformed.
