At current levels of use, how many years of coal do we have left?
130-150 years.
100
At current levels of use, how many years of oil do we have left?
47-50 years
100
What are the two main kinds of nuclear reactions?
Fusion and Fission
100
What is the most common nuclear fuel?
Uranium
100
What might happen to a human exposed to radiation posioning?
Could die, develop cancer, develop genetic mutations, etc.
200
At current levels of use, how many years of natural gas do we have left?
50-60 years.
200
The burning of all fossil fuels releases what into the air?
Carbon Dioxide, CO2
200
How do we dispose of Low Level Nuclear Waste?
Put it in "spill-safe" containers and bury them in the ground.
200
How do we dispose of High Level Nuclear Wastes?
We store them in steel-lined concrete pools filled with water.
200
How do all power plants work?
Some source of energy causes a turbine to spin and generate electricity.
300
What do we use natural gas for?
Burning for heat in our homes or as a fuel source for our stoves/clothes dryers.
300
What are two countries that have top Coal reserves?
USA, Russia, China, Australia
300
Why is Fusion not possible on Earth?
Only possible in stars because the temperature of a fusion reaction is several million degrees Celsius.
300
What prevents a nuclear explosion in a reactor?
Control rods
300
What are two advantages of nuclear energy?
Nuclear energy does not cause air pollution, does not release carbon dioxide into the air, is cost efficient over time.
400
Which fossil fuel generates the most energy when burned?
Natural Gas
400
What are two countries that have top Natural Gas reserves?
USA, Russia, Qatar, Turkmenistan, Iran
400
Draw or describe what happens during fission.
A free neutron collides with an atom of an element and causes it to split into two smaller elements. This reaction releases tons of energy.
400
What causes an Nuclear Explosion?
When the nuclear reaction chain is not controlled.
Uncontrolled nuclear reactions.
400
What are two disadvantages to nuclear energy?
Nuclear power plants are very expensive to build (6-9 billion dollars), can take up to a decade to build, and produce radioactive wastes that can be hazardous if not properly managed.
500
Why do we burn coal at power plants and not in our personal homes?
Power plants can filter out the sulfur produced from burning coal while our individual homes usually can't
500
What are two countries that have top petroleum reserves?
Venezuela, Saudi Arabia, Canada, Iran
500
What are three things every nuclear reactor will have?
Fuel rods, control rods, cooling system, reactor core, turbine
500
How much coal would you need to burn to match the amount of energy released when 1 gram of matter is converted into energy in a nuclear fission reaction?
3 millioin kilograms of coal.
500
What does "If you build it, it will leak," mean?
Eventually, any container built by mankind will leak if left unattended or is exposed to the elements.
