2. Why isn't fusion a casual source of energy?

  • It's only a hypothetical idea
  • Because it doesn't produce any
  • To produce the correct heat and pressure needed for fusion on Earth, it uses more energy than it makes
  • It can currently occur in space only and can't be taken to Earth

3. What kind of fusion was said by some scientists to have occurred in low temperatures?

  • Cold fusion
  • Ice fusion
  • No heat fusion
  • Who snows? (this is why we can't have nice things)

4. In 1989 scientists said they made fusion happen at 50 degrees celsius. Why?

  • because the experiment took place in space
  • other
  • there isn't any proof they did, so their experiments aren't valid. They could've lied or pulled of something really amazing but we'll never know.
  • because the experiment took place at the bottom of the ocean

5. What's a chain reaction?

  • when in a fission reaction nuclei are formed, neutrons released in the reaction undergo fission
  • I can't see a link to physics
  • when in a fission reaction the nucleus is formed, it splits and comes back together again
  • when in a fission reaction nuclei are formed, the energy released stimulates other nuclei to undergo a fission reaction
