Nuclear energy
C
Thermal energy
D
Electrical energy
Verified step by step guidance1
Understand that gasoline stores energy in the bonds between its atoms, which is released during combustion.
Recall that energy stored in chemical bonds is called chemical energy.
Recognize that nuclear energy involves changes in the nucleus of atoms, which is not the case for gasoline.
Note that thermal energy relates to heat, and electrical energy relates to electric charge flow, neither of which describe gasoline's stored energy form.
Conclude that gasoline is primarily an example of chemical energy because it stores energy chemically that can be released during reactions.
