Where does the sun get its hydrogen and helium?
Nuclear fusion. In the sun’s core, gravitational forces create tremendous pressure and temperatures. The temperature of the sun in this layer is about 27 million degrees Fahrenheit (15 million degrees Celsius). Hydrogen atoms are compressed and fuse together, creating helium.
Where does the sun get its energy from?
The sun generates energy from a process called nuclear fusion. During nuclear fusion, the high pressure and temperature in the sun’s core cause nuclei to separate from their electrons. Hydrogen nuclei fuse to form one helium atom. During the fusion process, radiant energy is released.
Where does the sun get its hydrogen?
What most people don’t know is that energy is the result of nuclear fusion happening in the core of the sun. That nuclear fusion leads to massive amounts of hydrogen being used as energy.
What does the sun consume to produce energy and helium?
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).
How does fusion make energy in the sun?
Nuclear Fusion reactions power the Sun and other stars. In a fusion reaction, two light nuclei merge to form a single heavier nucleus. The process releases energy because the total mass of the resulting single nucleus is less than the mass of the two original nuclei. The leftover mass becomes energy.
In which layer of the sun does hydrogen fusion occur quizlet?
Nuclear fusion occurs – A process in which particles of an element collide and form a heavier element, such as the fusion of hydrogen into helium that occurs at the Sun’s core.
How do we know sun is made of hydrogen?
The hydrogen and helium are in a gas form. You might wonder how we know that the sun is made of H and He gas. If you look at the light that comes from the sun after it has traveled through a prism, you will see that the light gets bent into a rainbow of colors.
What happens to the helium formed in the sun?
What happens to the Helium? Most stars, after converting a significant portion of their hydrogen to helium undergo an internal change. After the red giant phase, the Sun will lose its outer layers leaving behind its helium-rich core (called white dwarf), which will gradually cool over the lifetime of the Universe.
Can helium be made from hydrogen?
Most helium in the universe is helium-4, the vast majority of which was formed during the Big Bang. Large amounts of new helium are being created by nuclear fusion of hydrogen in stars….
|Naming||after Helios, Greek god of the Sun|

How much energy comes from the Sun?
At any moment, the sun emits about 3.86 x 1026 watts of energy. So add 24 zeros to the end of that number, and you’ll get an idea of how unimaginably large an amount of energy that is! Most of that energy goes off into space, but about 1.74 x 1017 watts strikes the earth.
