Nuclear Fusion, Fission and Half life Flashcards
1
Q
Name what happens at each step.
A
- Fuel produces heat, which is used to boil water to make steam.
- Steam spins a turbine.
- Turbine drives a generator and the generator makes electricity.
- Electricity goes to the transformers to produce the correct voltage.
2
Q
Energy is released by nuclear fission. Radioactive waste is also produced.
True or false?
A
True
3
Q
What sub-atomic particle must hit the nucleus of an atom to split it?
A
A neutron
4
Q
What must happen for fusion to take place?
A
Two nuclei must join together at
extremely high temperatures.
5
Q
Explain half life
A
The time it takes for the number of nuclei of the isotope in a sample to halve.
6
Q
What is Fusion?
A
Nuclear fusion is the joining of two nuclie. The two nuclei then form one bigger atom.
7
Q
What is Fission?
A
Nuclear fission is the splitting of an atom. Usually Heavy atoms such as uranium.
