What else can I help you with?
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.
Which property of the Solar Nebula was the most influential in giving the planets their characteristics?
The composition of the Solar Nebula, with materials such as gases, dust, and ice, largely determined the characteristics of the planets. These materials and their location within the nebula influenced factors like temperature, pressure, and density, which in turn affected the formation and composition of the planets.
What were the three most common substances present in the solar nebula?
The three most common substances present in the solar nebula were hydrogen, helium, and small amounts of heavier elements such as carbon, oxygen, and nitrogen. Hydrogen and helium comprised the majority of the nebula's mass, accounting for about 98% of it. These elements formed the primordial gas from which the Sun and the solar system developed. The heavier elements, produced in earlier generations of stars, contributed to the formation of planets and other celestial bodies.
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

What is the composition of nebula?
A solar nebula is made of (roughly) the same chemical composition as a star, namely: 70% Hydrogen 28% Helium 2% random molecules, for example Carbon-12 and Lithium.
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 are the most two common gases in air?
Nitrogen and Oxygen are the most common gases in the atmosphere.
What is the evidence that the Solar nebula hypothesis is probably correct?
The Solar nebula hypothesis is supported by several lines of evidence, including the observation of protoplanetary disks around young stars, which resemble the proposed structure of our early solar system. Additionally, the distribution of angular momentum in the solar system, with the Sun containing most of the mass and planets forming a flat disk, aligns with predictions of the hypothesis. The chemical composition of the planets, which reflects the solar nebula's materials, further corroborates this model. Lastly, computer simulations of the collapse of gas and dust clouds consistently produce outcomes that resemble the formation of our solar system.
Where did most of the gas in the solar nebula end up?
Most of the gas in the solar nebula ended up in the formation of the Sun, which contains about 99.86% of the total mass of the solar system. The remaining gas and dust contributed to the formation of the planets, moons, asteroids, and comets. During the early stages of solar system formation, some gas was also lost to space due to solar winds and other processes. Ultimately, the distribution of gas led to the diverse range of celestial bodies we see today.
How can nebula emit light?
In Nebulla Very energetic ultraviolet light from hot star excites a cloud of Hydrogen gas , UV radiation ionises the Hydrogen gas . The free electrons combine with protons forming Hydrogen and Red gas . In this way Nebula emits light .
