It's both a chemical change and a physical change.
Gasoline doesn't explode. In order for there to be an explosion, the combustion must happen in a sealed container. The gasoline combusts with oxygen in the atmosphere to form carbon dioxide, water vapor, nitrous oxides, and soot, along with a lot of heat. The liquid gasoline produces mostly vaporous products, and in a sealed container, will generate very high pressures.
The high pressure will cause the container to explode.

If gasoline poured into a tank an chemical change?
Gasoline being poured into a tank is not a chemical change.
Is less gasoline that remains in the gas tank as carbon dioxide physical change or chemical change?
The molecules are being altered so it is chemical change.
Is brewing a coffee chemical or physical change?
physical. the water being added simply soaks through the coffee, so there's no chemical change.
Is wheat being milled into flour a chemical change?
No. It is a physical change because the wheat's chemical composition does not change.
Is tarnishing of costume jewelry physical of chemical change?
Tarnishing is a chemical change in which the metal is being oxidized.
Is gasoline being evaporated a chemical reaction?
No. Evaporation is a physical process.
If gasoline poured into a tank an chemical change?
Gasoline being poured into a tank is not a chemical change.
Is gasoline being burned a chemical change?
yes
Is concrete setting a physical or chemical change?
It would be both. It's a physical change because it is changing state and a chemical change because water is being evaporated.
Is carbon dioxide being produced by the combustion of gasoline in an automobile engine a physical or chemical change?
When the gasoline burns, it forms water and various gasses, so it is a chemical change.
Is less gasoline that remains in the gas tank as carbon dioxide physical change or chemical change?
The molecules are being altered so it is chemical change.
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.
Is combustion a physical change or a chemical change?
Combustion is basically a chemical reacting with oxygen to become the oxide and water is produced. So when alcohol combusts, for example, it is changed (burned) to carbon dioxide and water. In other words, there is a chemical change.
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 a metal surface being ground a chemical change?
A metal Surface being ground is a physical change, not a chemical change.
Is milk being shaken into butter a physical change or a chemical change?
chemical change
Is being resistant to corrosion a physical or chemical change?
