Combustion is a chemical change because it involves the rearrangement of atoms and the formation of new substances. It is a exothermic reaction where a fuel reacts with oxygen to produce heat, light, and new chemical compounds.
This is a chemical process (combustion).
Exothermic reactions. E.g. combustion, oxidation
NO its a chemical change for it can't be reversed
A physical change is melting.A chemical change is combustion.
Water is identical to the standard enthalpy change of combustion of hydrogen because the combustion of hydrogen involves its reaction with oxygen to form water. The standard enthalpy change of this reaction is defined by the energy released when hydrogen combusts completely, which results in the formation of water as a product. Thus, the formation of water from hydrogen and oxygen under standard conditions directly correlates to the enthalpy change associated with the combustion process. Hence, the enthalpy change for the formation of water from its elemental components is equivalent to the enthalpy change of hydrogen combustion.
Chemical. Any type of combustion is a chemical change.
By explosion, you mean combustion I presume. Because combustion is a type of reaction, explosions are chemical changes.
This is a chemical process (combustion).
Exothermic reactions. E.g. combustion, oxidation
the paper undergoes combustion, a type of chemical reaction
Combustion (burning) is a chemical change.
Combustion clearly is a chemical change. In the combustion of a hydrocarbon, for example, you begin with the hydrocarbon and after combustion you end up with carbon dioxide (CO2) and water (H2O). This demonstrates that a chemical change has taken place.
Combustion (burning) is a reaction with oxygen (oxydation).
It is External-combustion engine.
Diesel Engine combustion chamber types : Swirl port combustion chamber type and Preignition port combustion chamber type.
Combustion is a type of oxidation; combustion is the reaction of organic materials when the products are carbon dioxide and water.
fuel and combustion makes a type of gas
