What energy transformations are used in a coal fired power plant?
Im Stuck please help. please describe what happens when it goes from chemical to thermal or whatever.
Answer: Chemical -> Thermal -> Kinetic -> electrical
Is the 'useful' pathway. A lot of it goes from chemical -> thermal and just escapes.
Energy is locked in the coal as 'chemical' energy. When it's burned with oxygen, you get 'thermal' energy which boils water. The steam then drives a turbine (which has a magnet or coil of wire on one end), which is 'kinetic'. The spinning turbine generates electricity, which is 'electrical'.
The turbine generates electricity because any moving magnet forces nearby electrons (like those in a copper wire) to move. Moving electrons = electricity!
