It isn't. This is a popular statement, but it is complete incorrect. Both mass and energy are conserved.
Energy: The energy was already available previously, but in another form (nuclear energy, which is a type of potential energy).
Mass: The heat or light that is produced is energy; it has an associated mass. For example, the photons (light) that leave the Sun not only take energy, but also mass, away from the Sun. This mass is exactly equal to the "missing" mass.
In nuclear fusion, mass is converted into energy via the process of fusion where atomic nuclei combine to form a heavier nucleus. This process releases a tremendous amount of energy as the mass of the resulting nucleus is less than the sum of the masses of the original nuclei. This missing mass is converted into energy according to Einstein's famous equation E=mc^2.

What happens to the mass of the sun that is lost during fusion?
Albert Einstein is credited with the equation that explains how the process of fusion provides energy. His equation, E = mc2 , stated that matter can be converted into energy and vice versa. In the fusion process that takes place in the sun, the hydrogen at the start of the process has more mass than the helium at the end of the process. Einstein explained that the lost mass is not actually lost, but has been converted to energy. This energy is the solar wind.
What percentage of the sun's mass gets converted into energy?
None. There is no such thing as mass-to-energy conversion: both mass and energy are conserved! The total mass before and after a nuclear reaction is the same; so is the total energy. For more information, read the Wikipedia article on "binding energy".
When nuclear fussion occurs some mass is lost where does it go?
The mass that is lost during nuclear fusion is converted into energy according to Einstein's equation, E=mc^2. This released energy is what powers the sun and other stars.
Nuclear reaction what is lost as energy is created?
In a nuclear reaction, mass is lost and converted into energy according to Einstein's famous equation, E=mc^2. This means that a small amount of mass is converted into a large amount of energy during nuclear reactions.
How are energy and mass related?
Energy and mass are related through Einstein's famous equation, E=mc^2, which states that energy (E) and mass (m) are interchangeable and can be converted into each other. This means that mass can be converted into energy, as seen in nuclear reactions, and energy can be converted into mass, as observed in particle physics experiments.
What happens to the mass lost in nuclear fusion?
The mass lost in nuclear fusion is converted into energy according to Einstein's famous equation, E=mc^2. This energy is released in the form of photons, such as gamma rays, and contributes to sustaining the fusion reaction.
Is the total mass after fusion greater or less than before fusion?
In nuclear fusion, the total mass after fusion is slightly less than the total mass before fusion. This is because a small amount of mass is converted into energy during the fusion process according to Einstein's mass-energy equivalence principle (E=mc^2).
What is preventing fusion energy from filling out current energy needs?
in neclear fusion, two hydrogen nuclei combine to create a helium, which has slightly less mass than the two hydrogen nuclei. The lost mass is converted to energy.
What During nuclear fusion is turned into energy?
In nuclear fusion, the mass of the atomic nuclei is converted into energy according to Einstein's famous equation E=mc^2. This means that a small amount of mass is converted directly into a large amount of energy during the fusion process.
What happens to the mass of the sun that is lost during fusion?
Albert Einstein is credited with the equation that explains how the process of fusion provides energy. His equation, E = mc2 , stated that matter can be converted into energy and vice versa. In the fusion process that takes place in the sun, the hydrogen at the start of the process has more mass than the helium at the end of the process. Einstein explained that the lost mass is not actually lost, but has been converted to energy. This energy is the solar wind.
What is true about the balance of mass in a fusion reaction?
In a fusion reaction, the total mass of the reaction products is less than the total mass of the initial reactants due to the conversion of mass into energy according to Einstein's famous equation E=mc^2. This difference in mass is known as the mass defect, and the lost mass is converted into energy during the fusion reaction.
What energy transformation occurs in nuclear fusion of hydrogen?
In nuclear fusion of hydrogen, the transformation of mass into energy occurs. This is in accordance with Einstein's equation E=mc^2, where a small amount of mass is converted into a large amount of energy.
In both fusion and fission what is converted into energy?
Mass. When you split a large atom (fission) into parts the mass of the parts is less then the original atom. The "lost" mass comes out as energy. When you combine two small atoms into a larger atom (fusion) , the larger atom has less mass then the two original atoms and the "lost" mass comes out as energy.
What is turned into energy when nuclear fusion?
In nuclear fusion, mass is converted into energy according to Einstein's equation, E=mc^2. When lighter atomic nuclei combine to form a heavier nucleus, the resulting nucleus is slightly less massive than the sum of the original nuclei, with the "missing" mass converted into energy.
The sun's energy is released when what is converted into energy?
The sun's energy is released when nuclear fusion converts hydrogen atoms into energy. This process involves the fusion of hydrogen nuclei to form helium nuclei, releasing large amounts of energy in the form of light and heat.
In a nuclear fusion reaction how does the mass of the products compare to the mass of the reactants.?
In a nuclear fusion reaction, the mass of the products is slightly less than the mass of the reactants. This loss of mass is converted into energy according to Einstein's E=mc^2 equation. The difference in mass is known as the mass defect.
Can energy converted into mass?
Yes. In a way, energy and mass are closely related; energy HAS mass, mass HAS energy. Energy gets converted into mass routinely in particle accelerators. The kinetic energy from the moving particles gets converted into new particles.
