Match the definition with the correct word. Object in space made of gases in which nuclear fusion reactions occur that emit energy.
A
planet
B
asteroid
C
star
D
comet
Explanation: 

Detailed explanation-1: -The energy released during a nuclear reaction is called binding energy. Binding energy is the minimum energy required to disassemble a system of particles into separate parts. Was this answer helpful?

Detailed explanation-2: -The main fuels used in nuclear fusion are deuterium and tritium, both heavy isotopes of hydrogen. Deuterium constitutes a tiny fraction of natural hydrogen, only 0, 0153%, and can be extracted inexpensively from seawater. Tritium can be made from lithium, which is also abundant in nature.

Detailed explanation-3: -Nuclear Fusion reactions power the Sun and other stars. In a fusion reaction, two light nuclei merge to form a single heavier nucleus. The process releases energy because the total mass of the resulting single nucleus is less than the mass of the two original nuclei. The leftover mass becomes energy.

Detailed explanation-4: -Stars are fueled by the nuclear fusion of hydrogen to form helium deep in their interiors.
