1. Why is U-235 (the uranium isotope with a mass of 235 amu) a special element and what is it used for?- Under some conditions U-235 can be spilt and yield a lot of energy. It can be used for nuclear fission.
2. Describe nuclear fission and how the famous equation E = mc2 relates to this process?- It is when the nucleus of an atom splits into smaller nuclei or fission products. It is an exothermic reaction and a lot of energy is released. It is the equation that is in accordance with converting the atom into energy.
3. Sketch the diagram of a nuclear power plant (or copy and paste it) and determine the functions of each of parts labeled A through H. Each part is not explicitly detailed in the article, so it is up to you to use the diagram to give your …show more content…
Define ore, define tailings, define mining, and give examples of what is “mined”.-
Ore- A naturally occurring solid from which metal can be extracted
Tailings- Residue
Mining- Obtaining coal or other minerals from a mine
Ex: Coal, ore, gold, silver, or copper 7. Describe these three big category types of mining: Surface mining (list 3 examples), Subsurface mining (list 3 examples), and in-situ leach mining used for uranium and copper.-
Surface mining- Digs at locations close to the Earth’s surface. Strip mining, open-pit mining, and mountaintop removal mining.
Subsurface mining- Digs down deep below Earth’s surface. Longwall coal mining, Room and pillar, Drift mine.
In-Situ Leach mining- Boreholes are drilled into deposit and they artificially dissolving minerals in a solid state. 8. Go to the second link given above to learn some about Uranium. Write a few comments about what you learned about Uranium.-
Uranium was discovered by Martin Klaproth in 1789
It is the main source of heat inside of the Earth
It has a melting point of 1132C
It occurs in most rocks 9. Go to the three Public Health links. Write a few comments about what you learned from
