how do we know that Nuclear Fusion occurs in the Sun, i mean we can't look inside the sun right?, so is Nuclear Fusion in the Sun, just a theory, which our scientists gave to explain the how energy produced inside the sun?, but there can be some other way by which sun produce its energy , which we still don't know about right?, so what my textbook said a fact, was in reality just a theory
Answers
Answer:
Yes nuclear fusion is the source of energy for the sun.Nuclear fusion is a nuclear reaction in which atomic nuclei of low atomic number fuse to form a heavier nucleus with the release of energy. It can be a only process with which sun can produce such a large amount of energy. It is a theory which is true.
Explanation:
Nuclear fusion is only possible when the core of a star(sun) is an intense environment. The pressures are enormous, and the temperatures can be greater than 15 million Kelvin. But this is the kind of conditions you need for nuclear fusion to take place. Once these conditions are reached in the core of a star, nuclear fusion converts hydrogen atoms into helium atoms through a multi-stage process.
