unit 3 topic 7 Flashcards
what is chemical energy
when a chemical substance transforms through chemical reaction
what is electrical energy
energy created from electric charge.
or electricity moving from one end to another
what is geothermal electricity
energy generated from the interior of the earth
why would a volcano be an example of geothermal electricity
because it creates energy and its from the earth
what is solar energy
energy powered from the sun
what is wind energy
energy generated by the wind
what is cogeneration
uses the waste heat to generate electricity
why would your heat vents be an example of cogeneration
because the heat doesn’t just come from thermal energy it also comes from electrical energy and chemical energy.
what is passive solar energy
uses the materials in the structure to absorbs and release solar energy
what would you use solar energy for
drying your clothes
what is active solar heating
uses mechanical devices like fans to distribute stored thermal energy
less solar energy is available during the winter than is summer so would you use active solar heating or passive solar energy
passive solar energy because it stores the energy
what are the two main problems from fossil fuel
pollutes the air
and mining for fossil fuels you damage the ground
what is on away of converting mechanical energy to thermal energy
when you press the car brakes
what is the green house effect
it is when heat from the earth is trapped and can not escape into space because of all the gases like carbon dioxide
