The longest lived stars are expected to undergo fusion reactions for billions of years. This is because they have lower mass and therefore burn their fuel at a slower rate than more massive stars. These stars, like red dwarfs, can have lifespans ranging from tens to hundreds of billions of years.

What kind of reaction does oxygen undergo fusion or fission?
Oxygen undergoes fusion reactions in the cores of massive stars, where it can fuse into heavier elements. Oxygen does not undergo fission reactions naturally.
Why uranium 235 is used in fusion reaction?
Uranium-235 is actually used in fission reactions, not fusion reactions. Uranium-235 is used in nuclear fission reactors because it is fissile, meaning it can undergo fission when bombarded by neutrons, releasing energy in the process. Fusion reactions, on the other hand, involve the merging of light atomic nuclei to form heavier ones, typically using isotopes of hydrogen like deuterium and tritium.
What happens when hydrogen particles collide?
When hydrogen particles collide, they may undergo fusion reactions where two hydrogen atoms combine to form helium, releasing a large amount of energy in the process. This is the process that powers the sun and other stars.
Reactions involving the particles in the nucleus of an atom are called what?
Reactions involving the particles in the nucleus of an atom are called nuclear reactions. These reactions can involve processes such as fusion, fission, and radioactive decay.
Nuclear reactions at very high temperature is known as?
Nuclear reactions at very high temperatures are known as thermonuclear reactions. These reactions involve the fusion of atomic nuclei, typically hydrogen isotopes, and release large amounts of energy. Thermonuclear reactions are responsible for the energy production in stars like our sun.
What kind of reaction does oxygen undergo fusion or fission?
Oxygen undergoes fusion reactions in the cores of massive stars, where it can fuse into heavier elements. Oxygen does not undergo fission reactions naturally.
In what state must matter exist for fusion reactions to take place?
Matter must exist in a state called plasma for fusion reactions to take place. Plasma is a highly energized state of matter in which electrons are stripped from their atoms, allowing for the nuclei to collide and undergo fusion. This state is commonly found in stars like our Sun.
Why uranium 235 is used in fusion reaction?
Uranium-235 is actually used in fission reactions, not fusion reactions. Uranium-235 is used in nuclear fission reactors because it is fissile, meaning it can undergo fission when bombarded by neutrons, releasing energy in the process. Fusion reactions, on the other hand, involve the merging of light atomic nuclei to form heavier ones, typically using isotopes of hydrogen like deuterium and tritium.
Is the sun made of gold?
No, the sun is not made of gold. It is primarily composed of hydrogen and helium gases. These elements undergo nuclear fusion reactions in the sun's core to produce energy and light.
Scientific evidence suggests that magnesium is formed by stars during?
Scientific evidence suggests that magnesium is formed by stars during nuclear fusion processes in their cores. As stars undergo fusion reactions, elements like helium and carbon fuse together to create magnesium through successive nuclear reactions. These elements are then released into space when the star reaches the end of its life cycle.
Which substance is most likely to undergo nuclear fusion?
Hydrogen is the most likely substance to undergo nuclear fusion. In the core of stars, hydrogen nuclei combine to form helium through the fusion process, releasing vast amounts of energy in the form of heat and light.
Where does our sun get its energy from?
Fusion reactions
Nuclide that have a high binding energy per nucleon are more?
Stable and less likely to undergo nuclear reactions or decay. This means they are more likely to remain unchanged over time compared to nuclides with lower binding energy per nucleon.
What are true reactions of the Sun?
They are fusion reactions, and The force to get the reactions to occur comes from gravity.
What are the names of the elements used to create the light in a star?
Hydrogen and helium are the main elements used to create light in stars through the process of nuclear fusion in their cores. These elements undergo fusion reactions to produce energy, which is emitted as light and heat.
The energy source of stars is primarily associated with?
The energy source of stars is primarily associated with nuclear fusion, where hydrogen atoms undergo fusion reactions to form helium, releasing a tremendous amount of energy in the process. This process occurs in the core of stars, where high temperatures and pressures allow fusion to take place.
Is solar energy is due to?
fusion reactions
