Which of the following is NOT an example of stored chemical energy?
biomass
fossil fuels
batteries
fire
How do solar thermal power plants generate electricity?
PV cells absorb thermal energy and convert it to electrical
heliostats direct light energy to turn water into steam
heliostats direct thermal energy to turn water into steam
PV cells absorb light energy and convert it to electrical
Why do incandescent (old fashion) light bulbs require more energy than LED (modern) light bulbs?
they use a 3-prong plug
they are larger than LED
more energy is converted to thermal instead of radiant
more energy is converted to radiant instead of thermal
According to the law of conservation of energy, what is the 1st energy conversion that takes place when fossil fuels are used to generate electricity?
mechanical energy transforms into electrical energy
look directly into the sun
thermal energy transforms into mechanical energy
stored chemical energy transforms into thermal energy
What is the difference in electricity generation between solar panels and power plants like wind, coal, and nuclear?
Solar panels produce more harmful radiation than the others.
Solar is non-renewable, while coal, wind, and nuclear are.
Coal, wind, and nuclear are cleaner than solar.
Solar panels don't use electromagnetic induction.
When does Newton's cradle have the most potential energy?
halfway in its upward swing
when it is initially pulled back
at rest
halfway in its downward swing
How could electromagnetic induction be produced? (2 options)
none of the above
with electricity being applied to a magnet
with a changing magnetic field surrounded by plastic wires
by rotating either the metal wire or magnetic field together
According to the law of conservation of energy, what is the 2nd energy conversion that takes place when fossil fuels are used to generate electricity?
stored chemical energy transforms into thermal energy
touching fire with your bare hands
thermal energy transforms into mechanical energy
mechanical energy transforms into electrical energy
True or False: Energy conversions are always 100% efficient.
False
What kind of resources are coal, water, and wood?
non-renewable resources
natural resources
renewable resources
man-made resources
Which Pokémon has the most thermal energy?
Charmander
Pikachu
Bulbasaur
Squirtle
Why is it important for battery technology to improve within the alternative energy field?
to clean the electricity from coal power plants
they'll explode if overused
to make electricity needed for windmills and solar to work
to store energy for when energy availability is lacking
Which Pokémon has the most electrical energy?
Pikachu
Charmander
Bulbasaur
Squirtle
Which Pokémon can harnesses solar power?
Charmander
Bulbasaur
Squirtle
Pikachu
Why don't bouncy balls return to their starting height when dropped without an applied force?
gravity becomes stronger near the ground
the inertia is greater than the starting potential energy
it should, but doesn't because gravity is acting on the ball
friction converts kinetic energy into thermal energy
Which of the following are needed to create fossil fuels?
heat, pressure, hundreds of years
heat, pressure, millions of years
heat, volume, millions of years
cold, pressure, thousands of years
True or False: A downfall to nonrenewable resources is that they can take as long as 10 years to replenish.
False
According to the law of conservation of energy, what is the 3rd energy conversion that takes place when fossil fuels are used to generate electricity?
thermal energy transforms into mechanical energy
getting struck by lightning
mechanical energy transforms into electrical energy
stored chemical energy transforms into thermal energy
How do solar panels generate electricity?
heliostats direct thermal energy to turn water into steam
PV cells absorb light energy and convert it to electrical
PV cells absorb thermal energy and convert it to electrical
heliostats direct light energy to turn water into steam
Which Pokémon uses hydropower?
Charmander
Pikachu
Squirtle
Bulbasaur
Why do most power plants use turbines to generate electricity?
to put heliostats in position to generate more electricity
to make the mechanical motion for electromagnetic induction
to create excessive amounts of static electricity
to stoke the coal fire needed to generate electricity
True or False: Fossil fuels are made from the fossils of dinosaurs and prehistoric plants.
False
