Hydrogen fuses into helium in the sun's core, where the high temperature and pressure conditions allow nuclear fusion reactions to occur. This process releases energy in the form of light and heat, which powers the sun and sustains life on Earth.
When different isotopes of hydrogen fuse in the sun, they produce helium nuclei. Specifically, the fusion process in the sun involves the conversion of hydrogen isotopes, such as deuterium and tritium, into helium-4 nuclei, along with the release of energy in the form of gamma rays and solar radiation.
In the sun, hydrogen atoms fuse together to form helium through a process called nuclear fusion. This process releases energy in the form of light and heat, which is what sustains the sun's brightness and temperature.
All stars fuse hydrogen into helium - the slight difference in atomic weight between 4 hydrogen atoms and one helium atom, is given off as radiation.
No, the sun is made primarily of hydrogen and helium, not burning gas. The sun's energy comes from nuclear fusion in its core, where hydrogen atoms fuse to form helium, releasing energy in the process.
Hydrogen is the fuel used by the sun, helium is the waste produced by hydrogen use in the fusion process
