Answer:
Chemical energy is transformed into heat energy.
Step-by-step explanation:
When a chemical bond is made between two chemicals, certain amount of energy is absorbed in order to from the bonds. When a chemical such as gasoline is burned, its chemical bonds are broken and the energy stored in those bonds are released in the form of thermal energy.
P.S.:
First three options are wrong because they violate the law of conservation of energy which states that the energy can neither be created nor be destroyed but it can be transformed into one form of energy to another form of energy.
Heat energy is created by the gasoline
False, Energy cannot be created
The total energy of the gasoline decreases.
False, Total energy must be conserved
Chemical energy in the gasoline is destroyed.
False, Energy cannot be destroyed
