Transcript of Energy Transformations

Energy Transformation
By: Anna Gabbert
Austin Harrington

Electrical to Thermal
When the oven is connected to an
electrical source
, the oven uses that electricity and transforms it to
heat
.
Electrical to Light
When the lamp is connected to an
electrical source
, the lamp runs the electricity through the filament in a light bulb and the electricity is seen as
light
.
Mechanical to Sound
The guitar player's
mechanical energy
is used to strum the
strings of the guitar
making it vibrate. These vibrations in the air cause
sound
.
Chemical to Nuclear
When an atomic bomb explodes it is the reaction of the
splitting of an atomic nuclei
. This chemical change is an example of
nuclear fission
.
Chemical to Mechanical
When she eats food it is
broken down in her stomach
and stored as energy. She then uses the energy to
exercise
which is mechanical energy.
Electrical to Sound
When somebody pushes the doorbell, an
electric signal
is sent to a speaker which translates the signal to a chime or ring, producing
sound
.
Mechanical to Electrical
The wind
blows the turbine
and makes it spin. This mechanical energy is used to spin a generator and then
produces electricity
.
Light to Thermal
The
light
produced from the filament in the heat lamp is being transformed into heat. The filament resists the flow of electricity and therefore
creates the heat
.
Electrical to Mechanical
When the fan is plugged in to an electrical outlet, that
electrical energy
is then used to turn the blades of the fan. The
turning of these blades
is classified as mechanical energy.
Thermal to Light
When the
stove top gets hot
, the atoms it is made up of begin to vibrate and the result of this vibration is the emission of
electromagnetic waves in the form of light
.
Nuclear to Electrical
At a nuclear power plant
nuclear fission
is used to turn water into steam. That steam is then used to power turbines that
generate electricity
.
Chemical to Light
A glow stick is a good example of chemical energy being transformed into light energy because inside the glowstick there are two chemicals seperated by a thin glass wall. When the wall is broken and the two mix they undergo a
chemical reaction
which results in a glow,
creating light
.
Thermal to Chemical
The
thermal energy
from the stove top is being transferred in to the water causing it to boil. When the water gets to a certain temperature it begins to evaporate and
becomes a vapor
. The water is undergoing a chemical change.
Mechanical to Chemical
When somebody uses
mechanical energy
to strike a match, the match undergoes a
chemical
reaction
and ignites
to create fire.
Light to Electrical
Solar panels work by allowing photons, or
particles of light
, to knock electrons free from atoms, generating a
flow of electricity
.
Sound to Electrical
When you speak into the telephone,
sound energy
from your voice is being changed into
electrical energy
as it flows through the telephone wires into the other phone (which will be changed back into sound energy).
Nuclear to Light
The sun is an example of nuclear energy because it creates its energy by
nuclear fusion
of hydrogen nuclei into helium. The sun becomes so hot from all this energy that it
creates light
.
Light to Chemical
The plant converts the
sun's
light energy

into
food
. This is a
process known
as photosynthesis.
Hydroelectric Energy
Hydroelectricity is the term referring to electricity generated by hydropower; the production of electrical power through the use of the gravitational force of falling or flowing water.
Worldwide, about 20% of all electricity is generated by hydropower.
10% of all the energy in the United States is hydroelectric.
Hydropower is the most efficient way to generate electricity.

Sound to Mechanical
If a speaker is at a
high volume
the vibrations in the air become more intense, therefore these vibrations can affect other objects and
cause them to move
.
Thermal to Mechanical
A steam train converts the
hot coals
thats put into it and creates steam. It then uses that steam to power its engines and
move from place to place.
What is an energy transfer/transformation?
An energy transfer occurs when any sort of reaction takes place.
Energy transfer:
Energy transformation:
The process of changing
one form of energy to
another.
