Energy is released by fusion of elements to heavier elements, i.e. fusion of hydrogen to helium in the sun's core.
I'm not sure what you mean by the 'composition of elements', but the hydrogen that our sun, like billions of other main sequence stars, is fusing right now is the leftover hydrogen from the Big Bang which, in billions of years' time, will eventually run out, and stars will have to fuse heavier elements, going up to iron (which means the universe will, eventually, die).
Bigger stars than the sun do fuse heavier elements, in 'layers', with the heaviest (Fe) in the middle, and the lightest (H) at the surface (look up onion structure star).
What else can I help you with?
Why is Venus a planet not a star?
Stars are mainly made of hydrogen and helium, and produce energy and light with atomic fusion at the core. Venus is made of rock and doesn't produce light, it just reflects light from the sun. Also, stars are hundreds of times bigger than Venus.
Stars produce energy by fusing hydrogen into what?
Stars produce energy by fusing hydrogen into helium through a process called nuclear fusion. This fusion reaction releases a tremendous amount of energy in the form of light and heat, which powers the star and allows it to shine.
How does nuclear fusion and other processes in stars lead to the formation of all the other chemical elements?
Nuclear fusion in stars involves the fusion of lighter elements to form heavier elements, releasing energy in the process. As stars evolve, they undergo processes like supernova explosions, which can produce even heavier elements through nucleosynthesis. This gradual accumulation of heavier elements in stellar environments eventually leads to the formation of all the chemical elements.
Which stars produce most of their energy by the CNO cycle?
Stars that produce most of their energy by the CNO cycle are predominantly those with a mass about 1.3 times the mass of our Sun or greater.Our Sun, and stars comparable in mass or less, predominantly use the proton-proton cycle.
Do all-star produce energy by nuclear fusion?
Yes, all stars produce energy through the process of nuclear fusion in their cores. This is where hydrogen atoms are fused to form helium, releasing vast amounts of energy in the form of heat and light.
What energy does the sun and stars produce?
the energy sun and stars produce is fusion.
How do hydrogen bombs and stars both produce nuclear energy?
Stars like our sun and hydrogen bombs produce energy through nuclear fusion.
Which two processes can generate energy to help a star maintain its internal thermal pressure?
Nuclear fusion is the primary process in stars that generates energy by fusing lighter elements into heavier ones. Gravitational contraction is another process where a star generates energy by converting gravitational potential energy into thermal energy. Both processes contribute to maintaining the star's internal thermal pressure.
What is the process occurring in stars to produce energy?
Nuclear fusion
What planet produces lots of energy?
The sun because it's hot and humans turn it into energy
Stars produce energy by fusing hydrogen into?
Helium atoms
Why is Venus a planet not a star?
Stars are mainly made of hydrogen and helium, and produce energy and light with atomic fusion at the core. Venus is made of rock and doesn't produce light, it just reflects light from the sun. Also, stars are hundreds of times bigger than Venus.
What process provides the heat?
Three processes produce heat. Contraction, in both stars and planets; radioactive decay, in planets, and nuclear fusion, in stars.
The stage in which stars produce energy through the fusion of hydrogen into helium?
main sequence
Stars produce energy by fusing hydrogen into what?
Stars produce energy by fusing hydrogen into helium through a process called nuclear fusion. This fusion reaction releases a tremendous amount of energy in the form of light and heat, which powers the star and allows it to shine.
How does a star work to produce light and energy?
Stars produce light and energy through a process called nuclear fusion. In the core of a star, hydrogen atoms combine to form helium, releasing a large amount of energy in the form of light and heat. This energy is what makes stars shine brightly in the sky.
What is different about a star from a planet?
Stars are bigger than planets until they finally collapse into dwarf stars. Stars are large enough to produce nuclear energy in their core, so they produce high amounts of heat and light.
