Do fusion reactions release energy in the sun?

How does fusion make energy in the Sun?

In the core of the Sun hydrogen is being converted into helium. 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.

How energy is produced in sun?

Solar energy is created by nuclear fusion that takes place in the sun. Fusion occurs when protons of hydrogen atoms violently collide in the sun’s core and fuse to create a helium atom. This process, known as a PP (proton-proton) chain reaction, emits an enormous amount of energy.

How is energy extracted from a fusion reactor?

The basic idea in all three cases is that the energy becomes heat, and is extracted using turbines, just like in a fossil fuel burning power station. On a microscopic level the energy is released in the form of kinetic energy of the helium nucleus and the neutrons that are given off.

Does fission occur in the sun?

Fission reaction does not normally occur in nature. Fusion occurs in stars, such as the sun. Byproducts of the reaction: Fission produces many highly radioactive particles.

What are the chemical changes taking place inside the sun?

The Source of the Sun’s Tremendous Energy

The source of the sun’s fuel is hydrogen and helium gases. Through a special chemical reaction, called nuclear fusion, the hydrogen gas is “burned” releasing an enormous amount of energy in the form of light and heat.
