Question

Describe in detail how the Sun produces its energy. Describe how that energy it transported from the core to the photosphere.

Answer 1

Because of its tremendous mass, the heat and pressure at the core of the sun is high enough to start a nuclear reaction. Two atoms of hydrogen, the most abundant substance of the sun, fuse together to make one helium atom with a bit of energy left over. This energy is in the form of a photon which bounces around the core and takes several years to reach the photosphere, the outer part of the sun, were it escapes into space until it hits the earth and we see it as sunshine.

Answer 2

The core of the Sun is considered to extend from the center to about 0.2 solar radii. It has a density of up to 150,000 kg/m3 (150 times the density of water on Earth) and a temperature of close to 13,600,000 kelvins (by contrast, the surface of the Sun is close to 5,785 kelvins (1/2350th of the core)). Through most of the Sun's life, energy is produced by nuclear fusion through a series of steps called the p-p (proton-proton) chain; this process converts hydrogen into helium. The core is the only location in the Sun that produces an appreciable amount of heat via fusion: the rest of the star is heated by energy that is transferred outward from the core. All of the energy produced by fusion in the core must travel through many successive layers to the solar photosphere before it escapes into space as sunlight or kinetic energy of particles.

nuclear fusion is the process by which multiple nuclei join together to form a heavier nucleus. It is accompanied by the release of a A LARGE AMOUNT of energy depending on the masses of the nuclei involved
