Gasoline burning is an oxidation reaction, a reaction with oxygen.
So, burning is a chemical change. And fire was the most important discovery of human beings.

What activity depends on a chemical change happening?
burning gasoline in a car engine
Is pumping up a tire a chemical change?
Gasoline combusts with air to produce CO2, CO, water, and others (depending on purity of gasoline). This releases heat energy, which is transfered to work energy by the expanding of the gas products, pushing the piston in the combustion cylinder. This in turn rotates the drive shaft, moving the car. All combustion reactions are forms of chemical change. Think of a campfire; the wood burns producing smoke, heat, and ash. What's left from the fire cannot be physically turned back into wood, and is therefore a chemical change. This holds true for all reactions, combustion and otherwise. In contrast, ripping a piece of paper or stretching a piece of puddy is a physical change because the ripped paper is still paper and the stretched puddy is still puddy.
When carbon dioxide comes from the fuel of the car is it a physical or chemical change?
chemical change
Most of the chemical energy of the gasoline burned in a car is not used to move the car but is changed into what?
Heat energy is mostly produced - and wasted.
Which statement best describes how the use of gasoline in a car relates to the discipline of chemistry?
The materials used come from the ground. The gasoline undergoes a change as it burns. A car uses the gasoline to move. All parts of the car are composed of chemicals.
Is the burning of gasoline in a car a chemical change or physical change?
Answer The burning of gasoline is a chemical change.
Burning gasoline in a car's engine a physical change or a chemical change?
Chemical but the energy released has physical consequences.
What activity depends on a chemical change happening?
burning gasoline in a car engine
Is the burning of fuel in a car a chemical or physical change?
It would be a chemical change because it is burning. Like a newspaper on fire.
Is gasoline being used in the engine of a car a chemical change?
Yes, the gasoline is chemically reacting with the oxygen in the atmosphere to create the heat needed to power the car.
What types of energy transformation are occurring when a car is burning gasoline?
Chemical energy to mechanical energy
What type of matter change occurs when gasoline is burned in a car?
it is a chemical change! (sexy right?;)
How many CFC's are produced by a car?
None at all. CFCs are a chemical compound not a byproduct of the burning of gasoline or diesel.
What type of change occurs when a car engine consumes gasoline - chemical or physical?
I don't think burning a gas to power a car is either Chemical nor Physical. If you burn gasoline to power a car, it is therefore a chemical AND physical change because both the chemicals and the look changes. However, a car being powered has nothing to do with the substance of gas being changed. If the car uses the gas to power itself, it'll turn the gas into gas again, so I'm not sure how this works. In conclusion, it's probably neither.
Is crashing a car chemical change?
No, though it is not easily irreversible like chemical reactions it is mainly a physical change, unless your car set in fire. (Burning is chemical)
How is starting a car a chemical reaction?
Because fuel is burned. Burning breaks down the chemical bonds of the fuel releasing some elements and making other chemical bonds.
Is running a car engine a chemical or physical change?
Chemical: hydrocarbons in the gasoline are burned.
