Describe at least three of the transformations from one form of energy to another that occur in changing coal at a power plant to the energy delivered to your home via an electrical wall outlet. Be sure to specify what form of energy is changed to what other form at each step.

@aaronq :) Thank you!!

Ahh this is best found easily by just googling :)

Try this link: http://en.wikipedia.org/wiki/Fossil-fuel_power_station

anonymous · Answer

oh! how would i search that? :P

anonymous · Answer

and okay, so one of the transformations is heat to mechanical energy? :/ or is that not it?not quite sure what it would be that i am searching for :(

perl · Answer

a hydro dam converts kinetic energy to mechanical energy and then mechanical energy is converted into electrical energy

perl · Answer

the falling water turns turbines which turn a dynamo

anonymous · Answer

Oh, so that is one of the transformations? and so i look to find similar things? like when you plug in a for example, charger into the outlet, kinetic energy turns into electrical energy? :/ is that correct?

perl · Answer

no, in an outlet its just electrical energy

perl · Answer

the kinetic energy i was speaking of was the water falling from a height

anonymous · Answer

ohh okay! what would two other transformations be? it has to be something that goes through several steps before it becomes mechanical energy, correct? It cannot just be electrical energy?

perl · Answer

that turns a turbine. the turbine turns a giant magnet which is inside a coil of wires

perl · Answer

the mechanical part could be the turbine

anonymous · Answer

ohhh, okay! :)

perl · Answer

turbine turns magnet, that induces electricity

anonymous · Answer

i am not sure about other ones though :(

the one you said makes sense now though :D

perl · Answer

:)

perl · Answer

fossil fuel plant is a little different. there they use coal or some other fuel to heat water, which turns to steam. the steam then is used to turn turbines which are attached to a giant magnet

perl · Answer

which then induces electricity

anonymous · Answer

okay! so in this case, it goes from kinetic energy to electric energy?

perl · Answer

yes

anonymous · Answer

yay!! :) what would another example be? :O

perl · Answer

well theres the chemical energy in the coal itself, that is being released by burning

perl · Answer

in the atomic bonds

perl · Answer

chemical energy is converted to...

anonymous · Answer

okay! what are the transformations of energy here? kinetic energy first, right?

anonymous · Answer

oh oops, chemical energy --> kinetic energy --> mechanical energy --> electrical energy ?

anonymous · Answer

i'm not very sure though @perl :/

perl · Answer

yes thats right

anonymous · Answer

ooh yay!! so would those three be acceptable to answer this problem? :O

perl · Answer

yes

anonymous · Answer

thank you!! :D
