How does the amount of work done on an automobile by its engine relate to the content of the gasoline?
HELP ME ASAP!

The energy derived from the content of the gasoline undergoing combustion will be greater than the amount of work the engine does on the automobile.

Explanation:

First of all, we need to know that the energy gotten from the gasoline undergoing combustion is what gives power to the engine. Now, the more the gasoline that undergoes combustion, the more the power that the engine will exert on the automobile. This means that larger vehicles will require more energy from gasoline to move.

Therefore, we can conclude that the energy derived from the content of the gasoline undergoing combustion will be greater than the amount of work the engine does on the automobile.
