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
- 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
