When Hydrogen Fuses In The Sun What Does It Make??


What happens to hydrogen in the Sun?

This is what happens to the hydrogen gas in the core of the Sun. It gets squeeze together so tightly that four hydrogen nuclei combine to form one helium atom. This is called nuclear fusion. In the process some of the mass of the hydrogen atoms is converted into energy in the form of light.

Does the Sun fuse hydrogen?

In its core the Sun fuses 620 million metric tons of hydrogen each second.

What heavier element is created when hydrogen atoms fuse together in the sun’s core?

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.Nov 3 2017

Where does the hydrogen in the sun come from?

Through most of the Sun’s life energy has been produced by nuclear fusion in the core region through a series of nuclear reactions called the p–p (proton–proton) chain this process converts hydrogen into helium.

How much hydrogen does the Sun fuse every second?

It fuses about 600 million tons of hydrogen every second yielding 596 million tons of helium. The remaining four million tons of hydrogen are converted to energy which makes the Sun shine.

How much hydrogen is in the Sun’s core?

Due to fusion the composition of the solar plasma drops from 68–70% hydrogen by mass at the outer core to 34% hydrogen at the core/Sun center. The core inside 0.20 of the solar radius contains 34% of the Sun’s mass but only 0.8% of the Sun’s volume.

How much energy does hydrogen fusion release?

Proton/proton fusion into deuterium accounts for 40% of the reactions by number releasing 1.44 MeV of energy for each reaction: 10.4% of the Sun’s total energy.

What elements will start to fuse together when hydrogen runs out?

When our Sun runs out of hydrogen fuel in the core it will contract and heat up to a sufficient degree that helium fusion can begin. Once that mass/temperature threshold is crossed the star begins fusing hydrogen into helium and will encounter one of three different fates.

Where does hydrogen fusion occur in the sun?

Inside the Sun this process begins with protons (which is simply a lone hydrogen nucleus) and through a series of steps these protons fuse together and are turned into helium. This fusion process occurs inside the core of the Sun and the transformation results in a release of energy that keeps the sun hot.Jun 16 2020

What happens to hydrogen atoms in the core of the Sun select the best answer s?

Answer: 4 hydrogens (protons) become 1 helium nucleus. … During its life the Sun will burn up the hydrogen in the core to produce energy helium and other particles.

Why does the Sun have hydrogen?

Through nuclear fusion the sun is constantly using up the hydrogen in its core:Every second the sun fuses around 620 million metric tons of hydrogen into helium. At this stage in the sun’s life its core is about 74% hydrogen.

How do stars create hydrogen?

Stars create new elements in their cores by squeezing elements together in a process called nuclear fusion. First stars fuse hydrogen atoms into helium. … Iron is the last element stars create in their cores and a kiss of death for any star with the the mass to make it to this point.

When did the Sun start fusing hydrogen?

Scientists estimate that it took the Sun only 100 000 years to gather enough mass in order to begin fusing hydrogen into helium. For roughly a few million years the Sun shone very brightly as a T Tauri star before it eventually settled into its current G-type main-sequence configuration.

How much hydrogen does the Sun fuse a day?

The sun consumes 5×1013T of hydrogen in one day.

How does hydrogen fuse into helium?

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 do we know the 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.

Which two elements make up the Sun?

Despite the controversy everyone agrees on the basics: The sun consists mainly of hydrogen and helium the two lightest elements. It generates energy at its center through nuclear reactions that convert hydrogen into helium.

What happens in the convective zone of the Sun?

In the convective zone the temperatures are cool enough—under 1 800 000 degrees Fahrenheit (1 000 000 degrees Kelvin)—that the atoms in the plasma there can absorb the photons coming outward from the Sun’s radiative zone. The plasma gets very hot and begins to rise upward out of the Sun.

What is fusion of hydrogen?

Fusion is the process that powers the sun and the stars. It is the reaction in which two atoms of hydrogen combine together or fuse to form an atom of helium. In the process some of the mass of the hydrogen is converted into energy.

Is fusion possible on Earth?

Normally fusion is not possible because the strongly repulsive electrostatic forces between the positively charged nuclei prevent them from getting close enough together to collide and for fusion to occur.

What kind of nuclear power is responsible for sunshine?

Thermonuclear fusion

Thermonuclear fusion is responsible for sunshine. Thermonuclear reactions take place at very high temperatures. In the Sun hydrogen atoms fuse together to form helium atoms. In this process radiant energy is produced and reaches the Earth.

What do stars burn after hydrogen?


Stars evolve because of changes in their composition (the abundance of their constituent elements) over their lifespans first by burning hydrogen (main sequence star) then helium (horizontal branch star) and progressively burning higher elements.

What would happen when all the hydrogen in the sun changes into helium Class 5?

Explanation: When all the hydrogen is converted to helium the Star rearranges itself its core shrinks and its outer layers expand depending on its initial mass the Star then transforms into a giant or a super-giant.

What happens when a star’s core runs out of hydrogen and why does this occur?

When the hydrogen supply in the core begins to run out and the star is no longer generating heat by nuclear fusion the core becomes unstable and contracts. The outer shell of the star which is still mostly hydrogen starts to expand. As it expands it cools and glows red.

How fusion works 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.

What is the main product of the fusion reactions in our sun?

The Sun is a main-sequence star and as such generates its energy by nuclear fusion of hydrogen nuclei into helium. In its core the Sun fuses 620 million metric tons of hydrogen and makes 616 million metric tons of helium each second.

What is the first step of the hydrogen fusion process?

The first step of the Hydrogen fusion process: a nucleus of Deuterium (2H) is formed from two protons with the emission of an antielectron and a neutrino. The basic Hydrogen fusion cycle involves four Hydrogen nuclei (protons) and two electrons and yields a Helium nucleus two neutrinos and six photons.

What are the products of step 1 of the hydrogen fusion process in the Sun Check all that apply?

What are the products of step 1 of the hydrogen fusion process in the sun Check all that apply? The nuclear fusion reaction inside the sun is as follows. Thus we can conclude that products of step 1 of the hydrogen fusion process in the Sun are isotope of hydrogen a neutrino and a positron.

What happens in Sun fission or fusion?

Fusion is what powers the sun. … Fission is the splitting of a heavy unstable nucleus into two lighter nuclei and fusion is the process where two light nuclei combine together releasing vast amounts of energy.

What fraction of the hydrogen atoms in the Sun are fused into helium each second?

In each nuclear conversion 4 hydrogen atoms are combined to produce a helium atom. This reaction occurs throughout the Sun and by this process our Sun converts 600 million tons of hydrogen into 596 million tons of helium every second.

Where was the hydrogen in the universe formed?

Big Bang
Between about 10-12 and 10-6 second after the Big Bang neutrinos quarks and electrons formed. Protons and neutrons began forming shortly after from about 10-6 to 1 second after the Big Bang. Within about 3 minutes after the Big Bang conditions cooled enough for these protons and neutrons to form hydrogen nuclei.Dec 12 2018

What would cause the sun to turn black?

They appear when energy from deep inside the sun is being blocked or prevented from reaching the surface. It’s being blocked by a strong magnetic field. So a sunspot is where a magnetic field gets so strong that it stops energy from inside the sun escaping to the surface.

What is sunlight made of?

Sunlight is composed of a spectrum of rays: visible light ultraviolet (known as UV) and infrared light. The light is measured in wavelength units – nanometers (nm) and millimeters (mm). Each of the different rays of the light in the spectrum has a different wavelength.
