2. If a chain reaction isn't controlled-
- there'll be a nuclear explosion
- living things will become ill
- there will be a risk of fire
- it prevents any of these other options
3. Only one neutron from each _____ can cause another _____
- fission
- fusion
- chain reaction
- atom
4. Why is fusion difficult?
- Nuclei may blow up if they get to the correct heat and pressure for fusion,so there is a low chance of them being able to fuse
- Nuclei have to be really close before it occurs, and as unless really high temperatures and pressures are reached to overcome this, the positive charges repel one another
- Because scientists haven't yet figured out how it works
- Trick question!
5. How are chain reactions controlled?
- other
- nuclei are kept stable
- use a different material to absorb neutrons,slwoing the recation down as there are fewer neutrons to stimulate more fission recations
- we don't know how to control a hypothetical chain reaction yet
