Two examples of energy transformations are shown. The energy transformations are similar because they both involve transformations that begin with chemical energy. Begin with electrical energy. Result in radiant energy. Result in mechanical energy.

The answers I think you are looking for is Gasoline or Fuel (chemical energy)

Explanation:

Energy transformation involves change or conversion of energy from one form to another. Having two examples of the same form of chemical energy, convert into two or more types of energy, the best example would be gasoline.

GASOLINE/FUEL → CAR BATTERY + LIGHT BULBS (TRAFFICATOR LIGHT)

(chemical)                     (electrical)               (radiant)

GASOLINE/FUEL → INTERNAL COMBUSTION ENGINE

(chemical)                   (mechanical)

c (diamond),

sio2 (quartz)
