When a mass of hydrogen has enough density, it begins to fuse the hydrogen atoms together. This produces heat and light. What is this classified as?
|
nebula
|
|
star
|
|
galaxy
|
|
planet

Explanation:
Detailed explanation-1: -This is called nuclear fusion . It takes four hydrogen atoms to fuse into each helium atom. During the process some of the mass is converted into energy.
Detailed explanation-2: -Stars produce their energy through nuclear fusion. For most stars, this process is dominated by a process called the “proton-proton chain, ‘’ a sequence of events that transforms four hydrogen atoms into one helium atom.
Detailed explanation-3: -Main sequence stars provide their energy by fusing hydrogen atoms together to produce helium. The more massive a star is, the more energy it requires to counteract its own gravity.
