Transformations
• The purpose of a nuclear power plant is to transform nuclear energy into
electricity. This is done is steps starting with a nuclear reaction which generates
heat to produce steam. The steam in turn is used to turn a generator which
finally produces electricity. If you were to create an energy transformation which
type of energy would come first? Second? Third? Fourth?
