Are you changing the nature of the gas by putting it inot a vechicle?
no
Putting gas in a vehicle involves a physical process, not a chemical reaction. When you fill up your vehicle with gasoline, you're essentially transferring a liquid fuel from the gas pump into the gas tank of your car. This process does not involve any chemical changes in the gasoline itself. The gas remains in its original form as a liquid, and it is being physically transported from one container (the gas pump) to another (the gas tank).
Chemical reactions, on the other hand, involve the breaking and forming of chemical bonds and result in the creation of new substances with different properties. Filling the gas tank in a vehicle does not cause any chemical transformations in the gasoline.
