Name 2 types of fuels for nucleur reactors
Uranium and plutonium
1 of 8
What is nucleus fission?
The splitting of a nucleus
2 of 8
Why are uranium and pluonium used for nucleut fission?
Because they have a large nucleus so therefore splits easily
3 of 8
What do uranium and plutonium have to absorb for nucleur fission?
A neutron
4 of 8
What is a chain reaction in nuclear fission?
When the energy released from one nuclei splittiong passes on energy, splitting others further down the line
5 of 8
What do the sun and stars use to release energy?
Nusleur fusion
6 of 8
What are stars formed from?
Massive clouds of gas and dust in space which is pulled together by gravity
7 of 8
What causes a star to begin a nucleur reaction?
When the gas falls together it becomes hot, starting a nucleur reaction. The energy released keeps the star hot
