Chemical but the energy released has physical consequences.
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.
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.
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.)
Burning chocolate is a chemical change because the heat causes the chemical structure of the chocolate to change, leading to the release of new compounds and altering the composition of the chocolate.
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.
Burning gasoline, or anything else for that matter, is a chemical change.
No. Burning gasoline, combustion, is a chemical 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.
Burnig things is always a chemical change.
Yes, gasoline undergoes a physical change when it evaporates before it burns. This change does not alter the chemical composition of the gasoline.
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.
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.
Gasoline burning is a chemical property because it involves a chemical reaction where gasoline is combined with oxygen to produce heat, light, and exhaust gases. This process results in a change in the chemical composition of the gasoline.
Burning is a chemical change.
Gasoline burning is an oxidation reaction, a reaction with oxygen.So, burning is a chemical change. And fire was the most important discovery of human beings.
