Why is nuclear a form of energy?

Energy is released in nuclear fission and fusion, this is a fact of the physics of the nucleus. This energy can be captured and harnessed as thermal energy (heat)


What is main disadvantage of fusion?

It requires almost as much energy to create nuclear fusion as the energy it creates. :)


Is fusion nuclear energy or chemical energy?

Nuclear fusion produces nuclear energy


Which two energy sources can help a star maintain its internal thermal pressure?

Nuclear fusion and radiation pressure are the two energy sources that help a star maintain its internal thermal pressure. Nuclear fusion in the star's core generates heat and energy, while radiation pressure from the intense photons produced by fusion counteracts the gravitational forces trying to collapse the star.


Does nuclear fusion violate the law of conservation of energy?

No, nuclear fusion does not violate the law of conservation of energy. In nuclear fusion, energy is released when atomic nuclei combine to form a heavier nucleus, and this process does not create or destroy energy, but rather transforms it from one form to another.


How does sun produce thermal energy?

The Sun produces thermal energy through nuclear fusion in its core. Hydrogen atoms combine to form helium, releasing large amounts of energy in the process. This energy is then radiated out as heat and light.


What energy transformation occurs in the sun?

In the sun, nuclear fusion reactions convert hydrogen into helium, releasing large amounts of energy in the form of heat and light. This process is the transformation of nuclear energy into thermal and electromagnetic energy.


How does the sun create energy it is core?

Nuclear Fusion from hydrogen in it core and helium


Is the sun thermal energy?

No antil it hits erth then it turns into thermal energy.


How does the sun make thermal energy?

The sun produces thermal energy through nuclear fusion in its core. This process involves the fusion of hydrogen atoms to form helium, releasing a tremendous amount of energy in the form of thermal radiation. This energy is then emitted from the sun and travels through space in the form of sunlight.


How does the sun produce radiant and thermal energy?

The Sun gets its energy from nuclear fusion - converting hydrogen-1 into helium-4.
