What else can I help you with?
What chemical reaction produces heat and energy in a star?
it is not a chemical reaction. It is a nuclear reaction and it is called fusion.
What two things are necessary for fusion reaction to take place in a star?
High temperature and high pressure are necessary for fusion reactions to take place in a star. The high temperature is needed to overcome the electrostatic repulsion between positively charged atomic nuclei, while the high pressure is needed to confine the high temperature plasma.
What energy would be used in a nuclear reaction in a star?
Nuclear fusion.
What kind of reaction occurs to produce energy inside a star?
Nuclear Fusion
Is it possible for fusion reaction to be happening at a planets core?
No. Fusion requires high concentrations of Hydrogen. Planets are made from substantially heavier elements. Additionally, a planet massive enough to begin a fusion reaction literally becomes a star.
Is it possible for fusion reaction to be happening at planet's core?
No. Fusion requires high concentrations of Hydrogen. Planets are made from substantially heavier elements. Additionally, a planet massive enough to begin a fusion reaction literally becomes a star.
What creates the heat and light in a star?
Nuclear fusion, in the star's core.Nuclear fusion, in the star's core.Nuclear fusion, in the star's core.Nuclear fusion, in the star's core.
What is a fusion reaction also known as?
Since they do not exist yet I do not believe they have any other names. Fusion does exist in nature so a sun or star could be considered a fusion reactor.
What is nitrogen fusion?
Nitrogen fusion is a nuclear reaction in which nitrogen atoms combine to form heavier elements, such as helium or carbon. This process occurs in the cores of massive stars during their later stages of evolution and is part of the sequence of reactions that produce the energy necessary to keep the star shining.
What keeps stars core hot enough for hydrogen fusion?
Initially, a star's core is heated by compression as a nebula collapses. Once fusion is up and going, the fusion itself provides the necessary heat.
Is a star a mineral?
basically it is a huge rock it is not a mineral or it is composed of gases Star is basically made of hydrogen gas which is constantly burning as fuel to carry out fusion reactions.
How many years does it take a star with mass of the sun to convert its hydrogen to its core?
No star will EVER convert ALL of the hydrogen to helium via nuclear fusion (the process that powers the star) because when the star is less than about 50% hydrogen, the helium gets in the way of the fusion reaction and the star begins to die out. The star will begin to shrink as the star's own gravity now is more powerful than the nuclear reaction, and the star will get more dense and will heat up. If the internal temperature and pressure gets high enough, the star will begin fusing helium into even heavier elements, becoming a red giant. The speed of this reaction depends on the original mass of the star.
