Is a car driving over a puddle a chemical or physical reaction?
When a car drives through a puddle of water, the change that takes place in the puddle is a physical change. Of course, chemical changes will take place in the engine of the car, but that's probably not what you are asking.
Is backing a car out of a garage a chemical reaction?
No, backing a car out of a garage is not a chemical reaction. It is a physical action that involves moving a vehicle in a particular direction. Chemical reactions involve the breaking and formation of chemical bonds, which is not the case when backing a car out of a garage.
When lead reacts with acid in a car battery is it a physical or chemical change?
Chemical.
When carbon dioxide comes from the fuel of the car is it a physical or chemical change?
chemical change
Why is smashing a car a physical change?
Smashing a car is a physical change because when the car is smashed it's, still the car. You didn't use any chemiclas to change it - the changes are only in appearance. So it's still a car until you use some kind of chemical to change it.
Is driving a car a chemical or physical reaction?
Driving a car involves both chemical and physical reactions. The combustion of fuel in the engine is a chemical reaction that produces the energy needed to move the car, while the physical interactions between the tires and the road surface enable the car to accelerate, brake, and turn.
Is running a car engine a chemical or physical change?
Running a car engine involves both chemical and physical changes. The gasoline fuel undergoes combustion, a chemical change, to release energy that powers the engine. This energy is then converted into mechanical work through physical processes such as movement of pistons and rotation of the crankshaft.
Does the pistons of a car move when the car is not moving?
it depends. if the car isn't moving, but the engine is still on, then yes the pistons are moving. if the engine is off, and the car isn't moving, then the pistons are still.

Burning gasoline in a car's engine a physical change or a chemical change?
Burning gasoline in a car's engine is a chemical change because it undergoes a combustion reaction that results in the production of new substances (carbon dioxide, water vapor, and other byproducts). This process involves breaking and forming chemical bonds, resulting in a chemical transformation.
What is it that makes a car engine work?
Combustion is the chemical reaction that causes a car engine to work. It is produced by fuel combining with oxygen which causes pressure and heat to turn the crankshaft of the engine. This essentially gets all of the parts of the engine moving.
Is pouring acid on a car chemical or physical?
chemical
Is gas burning in a car is a chemical or a physical?
physical
Is backing a car out of a garage a chemical reaction?
No, backing a car out of a garage is not a chemical reaction. It is a physical action that involves moving a vehicle in a particular direction. Chemical reactions involve the breaking and formation of chemical bonds, which is not the case when backing a car out of a garage.
When gasoline is burned in a car engine and the car moveswhat energy is generated?
The chemical energy (the fuel) turns into kinetic energy (the car moving) and heat energy(given off by burning fuel).
What does the engine do for a car?
it keeps it moving by petrol or diesel. its the only part that makes the car moving
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.
