Study Notes
Determining the Age of Fossils
- Scientists determine the age of fossils by studying the decay of isotopes and examining the ratio of stable and unstable isotopes.
Nuclear Power Generation
- Uranium-235 is used as fuel in nuclear reactors to generate electricity in nuclear power plants.
- When a slow neutron hits the heavy nucleus of Uranium-235, it splits into smaller nuclei, producing a significant amount of thermal energy.
- This heat energy is then used to generate electricity with the help of a generator.
Rooppur Nuclear Power Plant
- A new nuclear power plant is being constructed in Rooppur, Bangladesh, which is expected to produce 2,400 megawatts of electricity.
Effects of Radioactive Isotopes
- Radioactive isotopes can be very dangerous to humans in uncontrolled conditions, leading to cancer by causing genetic changes.
- Examples of disasters caused by radioactive isotopes include the atomic bombs dropped on Hiroshima and Nagasaki, and the Chernobyl accident in Russia.
Nuclear Reactions
- There are two types of nuclear reactions: fission and fusion.
- Fission involves a large nucleus splitting into two smaller nuclei, releasing energy as E = mc².
- Fusion involves two small nuclei combining to form a larger nucleus, also releasing energy as E = mc².
Relationship between Mass and Energy
- The source of all energy on earth is the Sun, which radiates energy through nuclear reactions.
- The equation E = mc² shows that a small amount of mass can be converted into a large amount of energy.
- Nuclear energy is much more powerful than chemical energy, with 1 gram of matter producing 9,00,00,00,00,00,000 joules of energy.
