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.
Gasoline being poured into a tank is not a chemical change.
The conversion of gasoline to carbon dioxide when it is burned is a chemical change, as it involves the breaking and forming of chemical bonds. This process releases energy in the form of heat and light.
physical. the water being added simply soaks through the coffee, so there's no chemical change.
Intensive because the price of gasoline is not going to change no matter how much you get.
Signs of chemical change are when a substance changes into a new substance. Like Paper being burned turns into gray powder. That is a chemical change.
No. Evaporation is a physical process.
Gasoline being poured into a tank is not a chemical change.
yes
It would be both. It's a physical change because it is changing state and a chemical change because water is being evaporated.
When the gasoline burns, it forms water and various gasses, so it is a chemical change.
The conversion of gasoline to carbon dioxide when it is burned is a chemical change, as it involves the breaking and forming of chemical bonds. This process releases energy in the form of heat and light.
Yes, the combustion of gasoline in a car engine is a chemical change. During combustion, gasoline reacts with oxygen to produce carbon dioxide, water, and energy, which are all different substances from the original gasoline.
Gasoline evaporation is a physical process.
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.
The color of gasoline, whether clear or pink, is a physical property. Physical properties are characteristics that can be observed or measured without changing the substance's chemical composition. In the case of gasoline, its color can vary due to the presence of additives or impurities, but this does not alter the fundamental chemical structure of the substance.
chemical change
A metal Surface being ground is a physical change, not a chemical change.
