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.
What else can I help you with?
Is evaporated gasoline a chemical change?
No, it would be a physical change. During a chemical change, substance(s) are changed into different substances. An example of a chemical change would be the rusting of iron but a physical change would be freezing water; or in this case, evaporation.
Is the burning of gasoline a physical change or a chemical change?
The burning of gasoline is a chemical change because it involves a reaction with oxygen from the air to produce carbon dioxide, water vapor, and energy. This process cannot be easily reversed to recover the original gasoline molecules.
If Gasoline gives off fumes is it a physical or chemical change?
Chemical change because its form is a new state then what it was when it started (:
Is spilled gasoline drying a chemical or physical change?
Gasoline evaporation is a physical process.
Is gasoline evaporating a chemical or physical change?
Physical change if I am correct.It will be a different form than the original.In your basic science classes you learned that if you for ex. have water as a solid,liquid and gas they are all the same thing because if solid ice=ice melts that means water,that if it is a liquid it is in its original state and that if it is a gas then it evaporates.The change is physical due to the appearance of it and the form it takes just changing.If a chemical reaction were to take place you would feel heat,sparks,etc.Hope this helps.
Does gasoline undergo a physical change before it burns?
Yes, gasoline undergoes a physical change when it evaporates before it burns. This change does not alter the chemical composition of the gasoline.
Is separation of water and gasoline a physical change?
No, it is a physical change. The water and gasoline retain their chemical and physical properties.
Is combustion of gasoline a physical change?
No, combustion of gasoline is a chemical change because it involves a chemical reaction between the gasoline and oxygen to produce carbon dioxide, water, and heat. A physical change involves a change in the physical state or appearance of a substance without altering its chemical composition.
Is a burned gasoline in a engine a physical or chemical change?
Chemical change
Is gasoline burns in an engine a chemical or physical change?
Chemical change
Consider the burning of gasoline and the evaporation of gasoline which process represents a chemical change and which represents a physical change?
The burning of gasoline represents a chemical change because it involves a reaction with oxygen to produce heat, light, and new chemical compounds. On the other hand, the evaporation of gasoline represents a physical change as it involves the gasoline changing from a liquid to a gas without any change in its chemical composition.
When gasoline evaporates is that a physical carnage or chemical?
This is a physical change.
Is evaporated gasoline a chemical change?
No, it would be a physical change. During a chemical change, substance(s) are changed into different substances. An example of a chemical change would be the rusting of iron but a physical change would be freezing water; or in this case, evaporation.
Is burning gasoline a physical or chemical change?
Burnig things is always a chemical change.
Is gasoline's ability to burn a chemical or physical change?
Neither - but when it does burn it's a chemical change.
Is gasonline burning a physical or chemical change?
Burning gasoline, or anything else for that matter, is a chemical change.
Is gasoline leaving an odor and drying a chemical or physical change?
Both
