Your solar system is thought to have formed from a nebula of dust and gas Most of this nebula condensed to form the sun What is primarily responsible for causing these materials to condense?
gravitational pull of nebula materials on each other
What are the most common gasses?
Nitrogen, Oxygen,Hydrogen, and Carbon Di-oxide are the common Gases in the Atmosphere.
What are the four most common gases in dry air are called?
nitrogen 78%oxygen 21%argon 0.9%carbon dioxide 0.04%
How does solar cell production pollute?
Depends on the kind of solar cell. Most types of solar cell use somekind of purified silicon substrate, and most types of solar cell use some combination of heavy metals, such as cadmium, tellurium, arsenic, indium, gallium, germanium, etc. In operation, solar cells cause no pollution whatsoever. But their production and what happens to them after use can cause pollution, and thus solar cells are certainly not without ecological footprint. There are a great number of very toxic chemicals used to make solar panels. These chemicals, if disposed of incorrectly, can do incredible damage to the environment. Gases, such as Phosgene, are used in their manufacture. The firs visible symptoms of phosgene poisoning include death. Accidents with gases such as this are far easier to occur then say a nuclear accident and do happen. Another major issue is the short life span of a solar panel. These panels lose output every year and after twenty years produce about 70% of what they did when new. They could quickly become a landfill disaster in the near future do the the volume of them needed to produce power for even one home.
When most solids liquids and gases are heated they?
expand
What percentage of the solar nebula's mass consisted of hydrogen and helium gases?
Roughly 98% of the solar nebula's mass consisted of hydrogen and helium gases. These two elements are the most abundant in the universe and are the primary components of stars like our sun.
What is the difference between a planetary nebula and a nebula that formed the solar system?
The solar system did not form from a nebula at all. Our solar system formed from a rotating cloud of gas and dust, our sun formed at the center and planets formed from the surrounding matter. when our sun became large enough to support nuclear fusion, the solar wind created blew away most of the gases present. A planetary nebula is formed after a star runs out of fuel (Helium) and collapses inward on itself due to the massive amount of gravity and the now unstable balance of the star. the pressure then becomes so great that the gases that had been pulled inward explode outward at an incredible speed. The Cats Eye Nebula is a good exampleFile:NGC7293_(2004).jpg
Which property of the Solar Nebula was the most influential in giving the planets their characteristics?
it dpends
What theory most likely explaines how the moon was formed?
I think the solar nebula theory.

gravitational pull of nebula materials on each other
Is a nebula different than a black hole?
It most certainly is. A nebula is a cloud of dust, hydrogen, and other gases where a black hole is a region of space from which nothing, not even light, can escape
Do comets and meteors have anything in common?
Yes they do, they are both rocks from outer-space. They both have a nucleus and they both travel in space. The thing that comets and meteors have in common is that they all travel in space and most of them all have not changed because of their formation in the solar nebula.
What are the most two common gases in air?
Nitrogen and Oxygen are the most common gases in the atmosphere.
What is the most common form of Solar Power?
Solar panels
Which one of the following objects is most like the planetesimals that formed in the solar nebula?
There is nothing on the list you provided that resembles them in any way.
What is the most famous nebula?
orion nebula
Why do Jupiter Saturn Uranus and Neptune contain hydrogen?
They do not have enough internal pressure.
