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.

Why pumping oil is physical change?
Pumping oil is considered a physical change because it involves a change in state or location of the oil without altering its chemical composition. The oil remains the same substance before and after pumping, only its position or state has changed.

Is cold water heating up to its boiling point a chemical change?
No, the process of cold water heating up to its boiling point is a physical change rather than a chemical change. This is because the molecules in water remain the same during the transition from liquid to gas; only their arrangement and energy levels change.
Why pumping oil is physical change?
Pumping oil is considered a physical change because it involves a change in state or location of the oil without altering its chemical composition. The oil remains the same substance before and after pumping, only its position or state has changed.
Where and how is the energy stored before it was transfered in pumping up a tire?
I assume you mean TIRE. The energy is usually stored up in whoever PUMPS UP the tire, and then you go lie down, to RE-CHARGE your energy cells!
Where and how was the the energy stored before it was transferred in pumping up the tire?
I assume you mean TIRE. The energy is usually stored up in whoever PUMPS UP the tire, and then you go lie down, to RE-CHARGE your energy cells!
Where and how was the the energy stored before it was transferred in pumping up the Tyre?
The energy was stored in the form of potential energy in the muscles of the person pumping up the tire. When the person exerts force on the pump, this energy is transferred to the air inside the tire, increasing its pressure and volume.
Pumping up a tire pascal the amount of air inside the tire?
This question is neither a question, nor a statement, nor rational. Try again.
What can a chemical change be speeded up by?
A chemical change can be speeded up by a catalyst
What speeds a chemical change up?
catalyst speeds up chemical change
Is a tire inflated with air a physical or chemical change?
physical change. the rubber is still rubber and the air is still air, so NO chemical change has occured
What happens to chemical change during a chemical change?
when a chemical change occurs, chemical bonds are broken up
Is heating up sulfur a chemical change?
It is not a chemical change, unless you heat it sufficiently to make it catch fire.
