Question

Inside stars in space, the nuclei of hydrogen atoms fuse together to form helium atoms. This represents which form of energy? electrical energy nuclear energy chemical energy radiant energy

Answer 1

Nuclear Energy

Step-by-step explanation:

The process where two nucleus fuse together to make a heavier nuclei and release a huge amount of energy is known as Nuclear Fusion and the energy released in the process is called Nuclear energy. Inside the core of the stars Hydrogen atoms fuse together to make Helium and thus release a huge amount of energy. This energy is then transmitted towards outer layer through radiation and convection.

Chemical Energy: The energy produced through a chemical reaction. Example: Batteries

Electrical Energy: The energy utilized or delivered by an electric system.

Radiant Energy: Energy of the EM waves.

Answer 2

nuclear energy

Step-by-step explanation:

Nuclear energy is the form of energy which is contained in the nuclei of the atoms.

In the nuclear fusion of the hydrogen, two (or more) hydrogen atoms fuse together into a helium nucleus. The final mass of the helium nucleus is lower than the sum of the masses of the original nuclei of hydrogen: this means that part of the mass has been converted into energy, according to Einstein's equation

`E=\Delta m c^2`

where

`\Delta m` is the variation of mass between final products and initial nuclei

c is the speed of light

The final energy is in the form of radiation/kinetic energy of the products, while the initial form of energy, which is contained in the nuclei of the atoms, is called nuclear energy.
