Question

Choose the correct statement regarding energy production in the interior of a star and energy production in a power plant. A star uses fusion as an energy source by building larger atoms from smaller atoms. A nuclear power plant uses fusion as an energy source by building larger atoms from smaller atoms. A nuclear power plant uses fusion as an energy source by breaking apart atoms. A star uses fusion as an energy source by breaking apart atoms.

Answer 1

Answer:

A star uses fusion as an energy source by building larger atoms from smaller atoms.

Explanation:

Nuclear fission and fusion are two processes at which an atomic nucleus is changed to produce energy. Fission is the process splitting heavy atomic into lighter atomic nuclei.

So, fusion is the combination of smaller atoms to form larger atoms and star uses this as source of energy.

Fusion is the process at which light atomic nuclei are merged or fused together to form heavier nuclei.

The energy source for all stars is nuclear fusion. In a nuclear fusion reaction, the nuclei of two atoms combine to create a new atom. Most commonly, in the core of a star, two hydrogen atoms fuse to become a helium atom.

Answer 2

Answer:

Option A) A star uses fusion as an energy source by building larger atoms from smaller ones

Explanation:

The energy source of stars is by nuclear fusion. Nuclear fusion is the process whereby two smaller nuclei combine to form a larger nucleus. The sun is an example of a star which is made up of mostly hydrogen and helium atoms. Two hydrogen atoms combine in the core of the star to form a helium atom.

Due to the fusion of hydrogen atoms that takes place in the sun to produce a helium atom, a great amount of heat is provided for the sun to utilize.

Nuclear power plants use heat produced during nuclear fission to heat water. In nuclear fission, atoms are split apart to form smaller atoms, thereby releasing energy.
