Question

Which statements about nuclear fusion are false? select the two correct answers. (1 point)

A) nuclear fusion releases large amounts of energy

B) the fuel for nuclear fusion is often uranium

C) nuclear fusion takes place in cores of stars

D) nuclear fusion is used to generate electricity at nuclear power plants

Answer 1

The false statements about nuclear fusion are that the fuel is often uranium and that it is used to generate electricity at nuclear power plants. The correct fuels for fusion are isotopes of hydrogen, and as of now, fusion has not been harnessed for practical electricity generation.

Step-by-step explanation:

The false statements about nuclear fusion are:

B) the fuel for nuclear fusion is often uranium

D) nuclear fusion is used to generate electricity at nuclear power plants

The fuel for nuclear fusion typically involves isotopes of hydrogen, such as deuterium and tritium, not uranium, which is primarily used in nuclear fission reactors. As of now, nuclear fusion is not yet a practical source for electric power generation, unlike nuclear fission, which is currently used in nuclear power plants.

Statement A) nuclear fusion releases large amounts of energy is true, as the fusion of light nuclei, such as hydrogen, releases energy. Also, statement C) nuclear fusion takes place in cores of stars is true, as the core's intense pressure and temperature enable hydrogen nuclei to overcome repulsive forces and fuse, powering the stars, including our sun.

Answer 2

B) the fuel for nuclear fusion is often uranium

D) nuclear fusion is used to generate electricity at nuclear power plants

Step-by-step explanation:

Nuclear fusion is the term used to describe a situation that causes the union of two atoms of light nuclei. This union creates a fusion of these two light nuclei, generating a heavier nucleus. This union of light nuclei releases a large amount of energy and is common to happen in the nuclei of stars, such as the sun, for example.

Even with the strong release of energy, nuclear fusion is not used to generate electricity in nuclear plants, nor does it even need to use uranium as fuel.
