1.
The energy of the Sun comes from
burning hydrogen gas
nuclear fission
chemical reactions
nuclear fusion
2.
Why are very high temperatures needed for fusion?
to overcome electrostatic repulsion between nuclei
to melt the nuclei
to make nuclei bigger
to cool the plasma
3.
Which is a main fuel for a fusion reactor on Earth?
Uranium-235
Coal
Deuterium
Plutonium
4.
A difference between fusion and fission is that fusion
splits heavy nuclei
joins light nuclei
needs no energy to start
produces carbon dioxide
5.
An advantage of fusion over fission is
it is already in use in all power stations
much less long-lived radioactive waste
it needs lower temperatures
it uses uranium
6.
The Sun emits 4 × 1026 J per second. Energy in 10 s is
4 × 1025 J
4 × 1026 J
4 × 1028 J
4 × 1027 J
