Nuclear fusion occurs when two small, light nuclei join together to make one heavier nucleus. The nuclei fuse together, and energy is released.
What is nuclear fusion?
The splitting of an atom
The joining of two light nuclei
The splitting of a heavy nucleus
Where does fusion occur naturally?
In stars such as the Sun
In power stations
Why does fusion only happen at very high temperatures?
Because it only happens in stars
To overcome the repulsion of the positive nuclei
To increase the speed of the reaction
Which of the following statements is false?
There is no radioactive waste with a fusion
Fusion does not emit carbon dioxide or other greenhouse gases into the atmosphere
Fusing nuclei together releases four times more energy per kg than burning coal, oil or gas
