What elements known to man deify gravity? Tue Oct 2, 2007 2:33:33 PM#41852Perm Link
I keep thinking about this in my classes. I have a theory that heat is the only elemental compound that deifies gravity to a certain degree. As we may all know heat is emitted from the sun and also heat rises due to its low density against cold air. Also, heat is generated from the earths core. So wouldnt heat be the only elemental compound that logically defies gravity? When heat is pulled down from the sun by the earth's gravitational pull, it does not fall entirely. Instead it uses cold air as a stepping stone to gain a higher altitude, therefore deifying gravity.
Heat is not an element. It is a property. It is energy.
You can think of magnetism the same way. A frog can be suspended in mid air with the right magnetic field, it doesn't mean that the frog can defy gravity. If you are interested in physical and such, check out what string theorists say. I find that very interesting.
2014 is going to be a good year. More content, more streamlining. Be a part of history!
Heat is indeed energy,not an element, and is considered to be a property that is very true. However, heat is comprised of elements, hence it s an elemental compound. It consists of more than one element. In order to have energy you need electrons with charges.In order to have electrons with charges you need elements.
I will definately look into that! For some reason I cant get hovering/levitation out of my mind.
Heat isn't comprised of elements. It's simply a form of energy, though it -can- be radiated -from- atoms and molecules. Electrons aren't necessarily needed to have energy either. Think of the disasters that would occur if your warmed your hands around an open flame. If the heat that radiates from the flame were simply comprised of just electrons, your palms would be ionized!
I'm not exactly sure what you mean by heat "defying" gravity, though. Heat itself isn't governed by any specific particle, therefore it's capable of transferring through conduction, convection, or radiating through open space, as in the case of the heat we receive from the sun.
My vocabulary is di...di...dimi...dimini..........killing itself.
Electrons aren't elements, but rather a negatively charged particle that is found surrounding an atoms nucleus (do atoms have nuclei? It's been a few years since Chemistry) Anyway, if you argued that "heat is the only thing that defies gravity on earth" you may be forgetting about other things like helium (think of balloons floating away).
In physics I learned that every mass has an attraction to every other mass around it. This gravitation attraction can be calculated by add the two masses (kg) together, dividing by their distance in meters squared, and multiplying the quotient by G which is something like 6.67 x 10^ -11. Perhaps the attraction between earth and certain particles (such as helium) is so low that it appears to defy gravity when in fact earths gravitational field is still acting upon it. That's just a thought, I could easily be misusing a simple law of physics. It's neat to think about though. Another possibility is the idea of things flowing from a high concentration to a low concentration. Like you said air is more dense than other particles. It could be that the less dense particles are rising atop the denser air that we breathe. I believe I've gotten to the point where I've over thought the whole thing though. Fuck.
Edit:Even still I'm not entirely sure that it's appropriate to say that these things are defying gravity rather than experiencing a lesser effect. Everything is related through mass, but our weight changes in different gravitational fields, perhaps a particles weight is so insignificant that it remains upright on layers of denser particles.
It is really interesting to think about, I may go search for the answer.
And I've found the answer and it makes sense. Ok, here it goes. A full explination:
The force of gravity on hot air is less than the force of cold air pushing the less dense particles (heat) upward. Therefore there is a net unbalancing force which causes the "heat" to rise. This all has something to do with buoyancy which I haven't learned about in physics yet. So I was partially correct in saying that the effect of gravity on minuscule particles causes an apparent rising.
