Global Warming
What is one cause of global warming?
Transportation - cars, trucks, planes, etc. releasing CO2 into the atmosphere
The capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms.
Energy
Burning a candle
Chemical energy -> heat energy + light energy
This type of energy is caused by changes to an atom's nucleus.
Nuclear Energy
Which is heavier... warm air or cold air?
Provide an example.
Warm air rises out of floor vents
What are two alternative forms of energy we could use instead of oil?
Solar, Hydro, Wind
Energy of motion
Kinetic Energy
Using a hot plate to boil water.
Electrical energy -> heat energy
This type of energy is stored in a substance that is released when the substance reacts.
Chemical Energy.
The transfer of heat through a solid material.
Conduction
Name three ways in which we can reduce our carbon footprint?
Carpool, eat locally sourced foods, use solar energy to heat and power our homes
Stored energy of position.
Potential Energy?
A hungry football player eating a large sandwich to use the food for energy.
Mechanical energy -> Chemical energy
Energy of moving electrons.
Electrical Energy
The transfer of heat by moving air.
Convection
What are the 3 R's?
For an extra 100 points... what does the "C" stand for?
Reduce, reuse, recycle, compost
What is a renewable resource and provide 3 examples.
Naturally replenished.
Biomass, wind, solar, geothermal, hydro
Using a solar-powered calculator.
Radiant energy -> electrical energy
To change from one form to another.
Transformation (chemical -> electrical)
The transfer of heat in the form of electromagnetic waves.
Radiation
Approximately how much does the water level rise each year?
3.2 millimeters
What is the Law of Conservation Energy?
Energy cannot be created nor destroyed.
A solar panel on the roof of a building used to heat and cool the building.
Radiant energy -> electrical energy
To move from one place or object to another.
Transfer (potential -> kinetic)
Heat from Earth's core
Geothermal Energy
