- Fission and Fusion
- How electricity is made
- Coal is burnt to release heat
- Fission- Uranium atom hit by slow moving neutron
- Uranium nucleus deformed by addition of neutron
- Unstable nucleus splits
- Daughter nuclei form-heat and gamma radiation are released
- Chain reaction
- Three fast moving neutrons
- Daughter nuclei form-heat and gamma radiation are released
- Unstable nucleus splits
- Occurs in extreme temperatures
- Fission reactor control- boron rods absorb neutrons, control reaction rate
- Uranium nucleus deformed by addition of neutron
- Fusion
- Extreme temperatures
- 1H+2H->3He
- Energy/mass conversion in the nucleus
- Tokomak-plasma required at 15,000,000 Degrees C but 2,000,000 Degrees C on Earth
- Pressure is needed
- How electricity is made
