Gravity will cause a star to become smaller, because it pulls matter towards the star's core and causes it to contract. On the other hand, nuclear fusion will cause a star to become larger, because it produces an outward pressure, pushing the star's matter outwards and causing it to expand.
What else can I help you with?
Stars are born when gravity pulls gas and dust together with enough pressure to ignite nuclear fusion true or false?
True.
What are all-stars driven by?
Stars are driven by Nuclear Fusion.
Can planets generate nuclear fusion?
Planets do not naturally generate nuclear fusion. Nuclear fusion occurs in stars, where the extreme heat and pressure at the core allows hydrogen nuclei to merge and form helium, releasing energy in the process. Planets lack the conditions necessary for sustained nuclear fusion reactions.
Where in the universe does fusion occur naturally?
Nuclear fusion is the process that powers stars, such as our sun.
What gas giant has nuclear fusion on it?
None. Nuclear fusion occurs in stars. Jupiter, for example, has all the right ingredients to be a star but as huge as it is, it doesn't have enough mass to generate the heat and internal pressure facilitate nuclear fusion. Hope this helps :-)
How does gravity initiate nuclear fusion in stars?
Gravity initiates nuclear fusion in stars by exerting a strong force that causes hydrogen atoms to collide and fuse together, releasing a tremendous amount of energy in the form of light and heat. This process, known as nuclear fusion, is what powers the sun and other stars, allowing them to shine brightly.
How do gravity temperature and pressure impact and affect nuclear fusion?
Gravity plays a crucial role in nuclear fusion by compressing and heating the stellar core to the high temperatures and pressures needed for fusion to occur. Higher temperatures and pressures increase the likelihood of atomic nuclei overcoming their mutual repulsion and fusing together. These conditions are found in the cores of stars, where gravity provides the necessary confinement and energy to sustain nuclear fusion reactions.
Can you explain the differences between nuclear fusion and gravity in terms of their roles in the formation and behavior of celestial bodies?
Nuclear fusion and gravity are two key forces in the formation and behavior of celestial bodies. Nuclear fusion is the process where atomic nuclei combine to release energy, which powers stars like the Sun. Gravity, on the other hand, is the force that pulls matter together, causing it to clump and form celestial bodies like planets and stars. While nuclear fusion powers the energy output of stars, gravity is responsible for holding these celestial bodies together and shaping their orbits and interactions. In summary, nuclear fusion fuels the energy of stars, while gravity shapes the structure and behavior of celestial bodies.
How does gravity effect the stars?
Please check the difference between the words "affect" and "effect". In this case, it should be "affect". Gravity keeps the stars together in the first place. It compresses them so much that they become hot and dense in their cores; enough so to start nuclear fusion.
What is the process by which stars burn brightly?
Stars get their energy from nuclear fusion - mainly, hydrogen to helium.Stars get their energy from nuclear fusion - mainly, hydrogen to helium.Stars get their energy from nuclear fusion - mainly, hydrogen to helium.Stars get their energy from nuclear fusion - mainly, hydrogen to helium.
Do stars combust?
Stars are not powered by combustion; they are powered by nuclear fusion, which is a fundamentally different and far more energetic process.
How did they become stars?
Gravity pulls the material together and it heats up to the point when self sustaining nuclear fusion starts.
What process produces the largest amount of energy given off by stars?
Nuclear Fusion
What are stars powered by?
Stars are powered by nuclear fusion
What are powers stars?
Stars are powered by nuclear fusion
How do fusion and gravity maintain stars in their current form?
Fusion pushes out, Gravity pulls in.
How do stars get their energy?
Nuclear Fusion
