Why does the sun stay hot in space even though there’s no oxygen?

Stellar nucleosynthesis is the process by which stars like the Sun create energy and produce elements through nuclear reactions. In the core of the Sun, the temperature and pressure are extremely high, which allows hydrogen atoms to undergo nuclear fusion and form helium. This fusion process releases a tremendous amount of energy in the form of heat and light. The Sun’s core temperature is about 15 million degrees Celsius, which is hot enough to overcome the electrostatic repulsion between positively charged nuclei and allow them to collide with enough energy to fuse. This process primarily involves the fusion of hydrogen nuclei (protons) to form helium nuclei, releasing energy in the form of gamma rays. <a href="https://medium.com/@Prakharvr/why-does-the-sun-stay-hot-in-space-even-though-theres-no-oxygen-3b1cf1962431">Visit Now</a>
