Additionally, each time the energy is changed to a different form (chemical to heat to electric to mechanical), some is lost.
(the energy; is changed; to a different form; T:each time) (some; is lost; T:each time the energy is changed to a different form (chemical to heat to electric to mechanical))
the energy some
is changed is lost
to a different form T:each time
T:each time the energy is changed to a different form (chemical to heat to electric to mechanical)
