As the electrons change orbits, they change energy levels. The energy is released into photons - which is the light of a fire.
When different elements oxidize, they give off different energies - thus different colors.
Not necessarily. Things sometimes change colors during a chemical reaction, but a color change is not sufficient evidence of a chemical reaction. You can add drink mix to water and the water turns colors, but it is not a chemical reaction, just a mixture.
Color change is considered a chemical change because it involves a transformation at the molecular level, where the chemical composition of the substance is altered, leading to a change in its color. This change is irreversible and indicates a chemical reaction has occurred.
A change in mass can be an indicator of a chemical reaction if there is a conversion of reactants into products with different mass compositions. For example, if gas is released during a reaction or if there is a change in the number of moles of substances present, there may be a noticeable change in mass.
You can be sure that a chemical change has occurred if there is a change in color, formation of a precipitate, evolution of gas, or absorption/release of heat during the reaction. These are all indicative of a chemical reaction where the substances are transformed into different compounds with new chemical properties.
A change in color can indicate a chemical reaction has occurred because the reaction might be producing or consuming a colored compound. This means that the chemical composition of the material has changed, leading to a different color being observed. The new color can be a result of the formation of new substances with different properties than the initial materials.
The change of color may be a sign of a chemical reaction.
- Color is a physical property and the change of color also.- Color change may be a sign of a chemical reaction.

Yes it is chemical change.
Color change is considered a chemical change because it involves a transformation at the molecular level, where the chemical composition of the substance is altered, leading to a change in its color. This change is irreversible and indicates a chemical reaction has occurred.
Change of shape can not be used to indicate a chemical reaction has happened. Examples of evidence of a chemical reaction are changes in odor or color.
Evidence of a chemical reaction include the following: formation of a precipitate formation of a gas change in temperature change in color
Yes, the signs of a chemical reaction are: gas, precipitation, heat, color change
The change in color indicates that a chemical reaction has taken place.
A change in mass can be an indicator of a chemical reaction if there is a conversion of reactants into products with different mass compositions. For example, if gas is released during a reaction or if there is a change in the number of moles of substances present, there may be a noticeable change in mass.
A chemical change. Color change is a good indicator of a chemical change.
Many materials can change colour according to the temperature without there being any chemical reaction taking place.
