Nuclear Fission.
In nuclear fission the nucleus splits into two smaller nuclei and energy is transferred.
1 of 16
Chain Reaction.
A series of events, each caused by the previous one.
2 of 16
Reactor.
A nuclear reactor is a device in which nuclear fission initiates a controlled chain reaction.
3 of 16
Control Rods.
Control rods are used in nuclear reactor controls the fission rates of uranium and platonium. They are made of chemical elements such as boron or silver which are capavble pf absorbing many neutrons without fissioning.
4 of 16
Coolant.
A liquid/gas that is used to remove heat from something.
5 of 16
Nuclear Fusion.
Nuclear fusion is the joining together of two atomic nuclei making a single stronger nucleus.
6 of 16
Protostar.
A very young star that is still gathering mass from its parent molecular cloud.
7 of 16
Neutron Star.
A compact star that can result from the gravitational collapse of a massive star after a supernova. (densest and smallest star)
8 of 16
Main Sequence.
Is a continuous and distinctive band of stars that appears on plots of stellar colour versus brightness.
9 of 16
Stars.
A luminous sphere of plasma held together by its own gravity.
10 of 16
Red Giant,
A dying star in the last stages of stellar evolution.
11 of 16
White Dwarf.
A stellar remnant composed mostly of electron-degenerate matter.
12 of 16
Black Dwarf.
A theoretical stellar remnant, specifically a white dward that has cooled sufficiently that no longer emits significant heat or light.
13 of 16
Supergiant.
The largest stars in the universe. They can be thousands of times bigger than our sun and have a mass up to 100 times greater.
14 of 16
Supernova.
A star that suddenly increases greatly in brightness because of catastrophic explosion that ejects most of its mass.
15 of 16
Blackhole,
Is a region in space where the pulling force of gravity is so strong that light is not able to escape.
