1. multiple choice 8 points

what is an advantage of using coal, oil, and natural gas (fossil fuels)? sev3a
they have toxic by - products
the amount is limited
they produce air pollution

1. multiple choice 8 points

the chemical energy stored in fossil fuels is converted into which form of energy in powerplants?
sev3b
solar energy
radiant (light) energy
electrical energy
kinetic energy

Explanation:

1.

Oil/petroleum is refined to make plastics, Vaseline, and many makeup products. Coal is mainly used for electricity generation and steel production. Natural gas is used for heating and power generation. Uranium is a radioactive element used in nuclear power, not a fossil fuel for these products.

In developing countries, wood and dung are commonly used as biomass fuels. Wood is readily available from forests and plantations. Dung (animal waste) can be dried and burned. Corn is more associated with bio - fuels like ethanol in some developed country contexts (e.g., US corn - based ethanol), but not as a major biomass fuel in most developing countries compared to wood and dung.

Fossil fuels (coal, oil, natural gas) are versatile. They can be used for transportation (oil - based fuels), electricity generation (coal, natural gas), heating (natural gas, oil), and as feedstocks in industry (e.g., oil for plastics). The fact that they have toxic by - products, are limited in amount, and produce air pollution are all disadvantages.

Answer:

oil / petroleum
