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.
Is burning gasoline in a lawnmower a physical or a chemical change?
Any burning is a chemical change. When gasoline (mostly a hydrocarbon called octane) burns, or combusts, it reacts with oxygen in the air to produce water vapor, carbon dioxide, and a bunch of heat energy, which your lawn mower engine harnesses to do work (turn the blade.)
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 gasoline being used in the engine of a car a chemical change?
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.
Is gasonline burning physical or chemical change?
Gasoline burning is a chemical change because it involves a chemical reaction where the molecules of gasoline combine with oxygen to produce heat, light, and new substances such as carbon dioxide and water vapor. This process is irreversible and results in the formation of different substances from the original gasoline molecules.
When gasoline is evaporated is it a chemical change?
No
Is gasoline that is evaporated a chemical change?
Nope.
Is gasoline being evaporated a chemical reaction?
No. Evaporation is a physical process.
Is gasoline being evaporated a chemical change?
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.
Is it a chemical change when a sugar is evaporated from water?
It is chemical change... It is also physical change........Thats because the appearance also changed.Its a chemical change because when something is evaporated, these steps include chemicals.
If gasoline poured into a tank an chemical change?
Gasoline being poured into a tank is not a chemical change.
Is the burning of gasoline in a car a chemical change or physical change?
The burning of gasoline in a car is a chemical change because it involves a reaction between the gasoline and oxygen to produce new substances (carbon dioxide, water, and heat). This results in a change in the chemical composition of the substances involved.
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.
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.
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
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.
