Damanpreet studied that Sun produce light and energy itself. Which process is responsible for production of light and energy? * 2 points
Answers
Answer:
The Core:
The core of the sun is the region that extends from the center to about 20–25% of the solar radius. It is here, in the core, where energy is produced by hydrogen atoms (H) being converted into nuclei of helium (He). This is possible thanks to the extreme pressure and temperature that exists within the core, which are estimated to be the equivalent of 250 billion atmospheres (25.33 trillion KPa) and 15.7 million kelvin, respectively.
The net result is the fusion of four protons (hydrogen nuclei) into one alpha particle – two protons and two neutrons bound together into a particle that is identical to a helium nucleus. Two positrons are released from this process, as well as two neutrinos (which changes two of the protons into neutrons), and energy.

Fusion is the reaction responsible for the production of light energy from the sun. It involves fusion of two hydrogen molecules to form helium.
1 H 1 + 1 H 1 → 2 He 4 + Energy.
