Energy is defined as the ability to
Do work or make change.
Which of the following exhibits kinetic energy
A ball rolling down a ramp
Chemical energy is stored in a match tip in the photo what has the chemical energy been converted into
Thermal and electromagnetic energy
The world’s most abundant fossil fuel is
Coal
The Middle East is especially rich in deposits of
Oil
Rock filled with a mixture of hydrocarbons is called
Oil sands
Which of the following is not caused by the burning of fossil fuel
A meltdown
Chemical compounds derived from oil are called
Petrochemicals
In a nuclear power plant which process is used to generate electricity
Nuclear fission
Mechanical energy is associated with the forces that hold parties together in the atoms nucleus
False – nuclear forces
Electricity is a primary source of energy
False – secondary
Fossil fuels form in an environment with the little or no oxygen
True
Cole is used to generate about half the electricity in the United States
True
In strip mining minors big shaft deep underground to reach the fossil fuels deposit
False – subsurface mining
When sulfide in rock surfaces react with oxygen and rainwater acid rain occurs
True
What is thermal energy
Results in an object becoming warmer if the particles in the object begin to move faster
What is combustion? What is the equation for the combustion of methane
Combustion is a chemical reaction where a fuel reacts with oxygen to produce heat, light, carbon dioxide, and water.
For methane, the equation is:
CH₄ + 2O₂ → CO₂ + 2H₂O + energy.
What are the advantages of coal as a source of energy?
Coal is easy to find, cheap, gives a lot of energy, and is used with reliable technology to make electricity.
Over the next few decades what is likely to happen to the world’s production of oil?
Oil production is likely to decrease as reserves shrink and renewable energy use increases.
Identify at least three ways in which fossil fuels can damage human health
Climate change air pollution and water contamination
What is mountain top removal?
Mountaintop removal is a mining method where the top of a mountain is blasted off to reach coal, damaging the environment.
Identify two reasons why energy conservation is important to practice.
Reduces environmental impact decrease pollution and saves resources like fossil fuel
