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.
Combustion is a chemical change because it involves a chemical reaction between a substance and oxygen to produce new substances. This process releases heat and light energy.
Something being combustible is a chemical property, not a change.
combustion is a chemical change.
combustion (burning) is a chemical change.
The base process of combustion is oxidation, a chemical change.
Gasoline is mostly converted into energy when this happens, so it is a chemical change. You can assume that a process is a chemical change if it involves combustion, most of the time.
chemical change
Physical
It is a phiscal change because the combustion doesn't change. I'm in the 7th grade and nobody older than me answered this question! That is a shame!
Yes, fireworks involve a chemical reaction where the materials inside the firework combine to produce light, heat, and sound. This chemical reaction is not reversible, so it is considered a chemical change rather than a physical change.
Combustion of wood is a chemical change because it involves the breaking of chemical bonds in the wood molecules to form new substances (such as carbon dioxide and water vapor). A chemical change results in the formation of new substances with different chemical properties than the original substances.
Supporting combustion is a chemical change because it involves a chemical reaction between the fuel and oxygen to produce heat, light, and new chemical compounds. This reaction results in the formation of new substances different from the original fuel.
The smoke produced by a vehicle is a combination of physical and chemical changes. The combustion of fuel in the engine is a chemical change that produces gases, while the dispersal of these gases into the air involves physical changes such as condensation and diffusion.
Combustion (burning) is a chemical change.
A physical change is melting.A chemical change is combustion.
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.
Yes, fireworks involve a chemical reaction where the materials inside the firework combine to produce light, heat, and sound. This chemical reaction is not reversible, so it is considered a chemical change rather than a physical change.
It is a phiscal change because the combustion doesn't change. I'm in the 7th grade and nobody older than me answered this question! That is a shame!
the physical comes from the chemical explosion
Combustion is a chemical change, not a physical change. It involves a chemical reaction where a substance reacts with oxygen to produce heat, light, and new chemical compounds.
It is a chemical change; burning (combustion) is a chemical process.
No combustibility- it is a property. However, COMBUSTION is a chemical change.
Combustion is a chemical change, so the burning of a tree will be a chemical change.
Chemical, an explosion is essentially extremely fast combustion which is a chemical reaction.
If you burn something it is a chemical change, however if you melt of boil it, it is a physical change.
