Stellar equilibrium relies on fusion and gravity to maintain stars in their current form?
Yes, a stable star is in equilibrium, called hydrostatic equilibrium, when the outward pressure from heat caused by core fusion processes balances the inward pull of gravity. There are other factors which alter the form of stars such as their rotation or gravity from external sources such as a nearby mass.
Are stars born when gravity pulls gas and dust together with enough pressure to ignite nuclear fusion?
Yes, stars are born when gravity pulls gas and dust together from a nebula.
What would happen if we didn't have gravity?
Without gravity, none of the stars or planets would maintain their forms. Gravity allows the Sun to maintain its energy generation while remaining as a single mass. Gravity allows the Earth to hold its atmosphere. Indeed, gravity is the force that forms stars and planets, although the trigger that begins the process is still unclear.
How did they become stars?
Gravity pulls the material together and it heats up to the point when self sustaining nuclear fusion starts.
Is enery released in stars as a result of fusion reactions?
Yes, according to current thinking, which seems pretty persuasive. Most energy in stars is released from the fusion of different forms of hydrogen to form helium.
Stars are born when gravity pulls gas and dust together with enough pressure to ignite nuclear fusion true or false?
True.
Are all-stars fusion reactors?
Yes, stars are fusion reactors.
Which of these develop when gravity pulls gas and dust together with enough pressure to ignite nuclear fusion?
Having some trouble seeing your list of choices from here.But stars do.
Is it true that fusion provides a force that balances the inward force of gravity in creating stars?
Sort of - there energy released by the fusion occurring in the core of the star balances the force of gravity trying to make the star collapse inwards.As a star evolves this balance changes and the size of the star will change over time. When the material available for fusion runs out in the core, gravity wins the fight.
What force is responsible for crushing or collapsing stars?
A supernova is caused the the fusion of (in most cases helium) molecules in iron. Once you reach iron, you can't use fusion. Thus, the star can't produce the energy to keep it stable and gravity causes it to collapse.
What is gravity's job in the universe?
Gravity basically makes things come together, and keep together. For example, due to gravity: * Galaxies form and keep together * Stars form and keep together * Stars get hot enough for nuclear fusion to start * Planets form and keep together * Planets keep around their stars, instead of wandering off into space
What triggers nuclear fusion stars?
Fusion in stars are usually the result of gravity.Once a mass of hydrogen accumulates enough mass, the gravity of all that mass compresses the core of the star to the point that the hydrogen atoms there begin fusing into helium. The process then cascades outward, and the end result is a star.
