Gravitational pressure.
A large mass of gas has a lot of internal gravity, and as it falls together, it gets compressed and heats up. At some point, the gas gets so hot that all the electrons are stripped away from the atomic nuclei, and the gas becomes unimaginably dense and hot - and eventually it gets hot enough that the hydrogen nuclei begin to fuse into helium, generating even more heat and pressure. At that point, the gas cannot be compressed any further, because the energy generated in fusion is pushing the nuclei apart, and the star reaches an equilibrium between the gravitational pressure inward and the radiation pressure outward.
What else can I help you with?
Which of these develop when gravity pulls gas and dust together with enough pressure to ignite nuclear fusion?
Stars develop when gravity pulls gas and dust together with enough pressure to ignite nuclear fusion. This process starts in the core of the collapsing cloud, where the temperature and pressure become high enough for nuclear reactions to occur, initiating the star's life cycle.
Can the moon produce light through internal nuclear combustion?
No. The moon does not produce any light of its own. It only reflects light from the sun. It does not have enough mass to ignite nuclear fusion, nor is it of the right composition. Finally, nuclear fusion and combustion are two completely different processes.
Why are lower-mass stars unable to ignite more massive nuclear fuels such as carbon?
Lower-mass stars are unable to ignite more massive nuclear fuels such as carbon because they lack the temperature and pressure conditions required for fusion reactions involving heavier elements. These reactions typically require higher temperatures and pressures that are only present in the cores of more massive stars. As a result, lower-mass stars are limited to burning lighter elements like hydrogen and helium through processes like the proton-proton chain.
Is it possible to make Jupiter a star if you applied more mass to it?
No, Jupiter does not have enough mass to become a star. It is a gas giant planet made primarily of hydrogen and helium, but it would need at least 80 times its current mass to ignite nuclear fusion and become a star like our Sun.
A fragment of a collapsing gas cloud that comes to equilibrium with a central temperature of 4 million k becomes what?
A fragment of a collapsing gas cloud that comes to equilibrium with a central temperature of 4 million K becomes a protostar. As gravity causes the gas to contract and heat up, nuclear fusion reactions ignite in its core, marking the birth of a star. The protostar will continue to evolve as it balances the inward pull of gravity with the outward pressure from nuclear fusion.
Could Jupiter ignite and become a star?
No, Jupiter cannot ignite and become a star. It does not have enough mass to sustain nuclear fusion like a star.
Which of these develop when gravity pulls gas and dust together with enough pressure to ignite nuclear fusion?
Stars develop when gravity pulls gas and dust together with enough pressure to ignite nuclear fusion. This process starts in the core of the collapsing cloud, where the temperature and pressure become high enough for nuclear reactions to occur, initiating the star's life cycle.
Why can't a planet be a star?
A planet does not have enough mass to ignite nuclear fusion.
Stars are born when gravity pulls gas and dust together with enough pressure to ignite nuclear fusion true or false?
True.
What caused the failed star Jupiter to not ignite and become a fully-fledged star?
Jupiter did not become a star because it lacks the mass needed to sustain nuclear fusion in its core. Stars need a certain amount of mass to generate enough pressure and heat for nuclear fusion to occur, and Jupiter's mass is not sufficient for this process to take place.
Is Jupiter a failed sun?
No, Jupiter is not a failed sun. It is a gas giant planet that did not have enough mass to ignite and sustain nuclear fusion like a star.
Why doesn't nuclear fusion occur in the core of planets?
Nuclear fusion requires extremely high temperatures and pressures, which are typically found in stars like the Sun. The cores of planets do not have the same conditions necessary for sustained fusion reactions to occur, so the fusion process is not able to take place there.
What temperature does jet fuel ignite?
It is enough for a spark to ignite any fuel.
Do inert gases ignite spontaneously?
No. Inert gasses cannot ignite at all. They very rarely undergo reactions of any sort.
Can the moon produce light through internal nuclear combustion?
No. The moon does not produce any light of its own. It only reflects light from the sun. It does not have enough mass to ignite nuclear fusion, nor is it of the right composition. Finally, nuclear fusion and combustion are two completely different processes.
What would happen if you ignite a nuclear bomb in a volcano?
You get a rather large explosion.
Could you ignite Neptune and create a small sun?
No, it is not possible to ignite Neptune to create a small sun. Neptune is a gas giant planet, primarily made of hydrogen and helium, while a sun is a massive star that undergoes nuclear fusion producing light and heat. The size and composition of Neptune are not conducive to creating a star.
