nonrenewable/nucleus
| Question | Answer |
|---|---|
| what is not a fossil fuel | wind |
| all fossil fuels are | nonrenewable |
| energy from the sun comes from nuclear | fusion |
| about --- percent of the energy used in the us comes from burning fossil fuels and nuclear energy | 85 |
| the many different compounds that are found in --- are separated in a process called fractional distillation | petroleum |
| energy from a nuclear power plant comes from a nuclear | fission |
| coal exists in what state of matter | solid |
| nuclear waste must be disposed of carefully so that this wont be leaked into the environment | radiation |
| this has uses other than energy such as plastics and lubricants | petroleum |
| how efficient is coal power plants | 40-45 % |
| how efficient is natural gas plants | 50-60% |
| how efficient is nuclear power plants | 45-50% |
| what is the most common radioactive fuel that is used in nuclear reactors | u-235 |
| what is the function of the control rods in a nuclear reactor | to control the nuclear reactions (how much power) |
| how is the fossil fuel from the nuclear reactor stored | underwater, spent fuel cools ( keeps cool and absorbs radiation) |
| identify the energy transformation that takes place from the time a uranium atom is split until electricity is produced | NE_ TE_ME_EE |
| describe the five stages in the production of electrical energy at a fossil fuel burning power plant | CPE in fossil fuels burned, TE out of water goes to steam and turns turbine. ME turns generator, EE electromagnetic induction |
| why are fossil fuels considered nonrenewable resources | they are not replaced as fast as we are using them |
| why is nuclear fusion not currently used as an energy source on earth | high temp. hard to control |
| the info of a smoke detector says that it should be returned to the manufacturer and not thrown away in a trash can. why | it has radiation |
| pros of coal | affordable, abundant, reliable |
| cons of coal | contains impurities, ash left behind, nonrenewable |
| pros of natural gas | abundant, cleanest burning fossil fuels, 40-45% efficient |
| cons of natural gas | highly flammable, nonrenewable, costly to process and store |
| pros of nuclear fuel | low operating cost, abundant, reliable and safe, high energy content |
| cons of nuclear fuel | expansive, takes long time to build,nuclear waste storage |
