Final answer:
Gasoline combustion produces carbon dioxide, water vapor, and a significant amount of heat, meaning all options A, B, and C are correct.
Step-by-step explanation:
When gasoline burns, the chemical reactions transform it into several products. The predominant products are carbon dioxide and water vapor, as it is a combustion reaction involving hydrocarbons reacting with oxygen from the air. Additionally, this reaction releases a significant amount of heat energy, which is utilized in engines to perform work. Therefore, the correct answer to what gasoline turns into when it burns is D. All the above: water vapor, heat, and carbon dioxide.
