No. Any object that is hot enough will produce light, regardless of what heated it.
Essentially oxygen does not produce light ... light itself is an energy, and cannot be created only changed
A reaction is considered chemical when bonds between atoms are broken and new bonds are formed, resulting in a change in the chemical composition of the substances involved. Physical changes, on the other hand, do not involve changes in the chemical composition of the substances.
By chemical methods, such as electrolysis.
Some chemical changes when you are cooking are:burning the foodOVERcooking itUNDERcooking itsorry for only three examples. those are the ones that i can only think of so far.
The bonds between hydrogen and oxygen atoms of individual water molecules do not change when liquid water changes to ice. This is a physical change called freezing, and does not cause any chemical changes to occur. Only chemical changes can cause changes in chemical bonds.
yes
Only if you include heat (magma, meteors, light bulbs), charged particles (lightning, aurora) and electroluminescence (LED) under "chemistry". None of these produce light by what we normally think of as a chemical reaction.
When you break a light stick, it is a physical change, not a chemical change. The breaking of the light stick only changes its physical state but does not alter its chemical composition. This is because the chemical reactions that produce light in a light stick have already occurred when the stick was activated, and breaking it does not initiate any new chemical reactions.

There are no physical changes. there are only chemical changes.
If light is produced when two substances are mixed, it is most likely a chemical change. Chemical changes involve the formation of new substances with different properties, whereas physical changes typically only affect the state or appearance of a substance without altering its chemical composition.
The moon does not produce light. It only reflects light from the sun.
Nuclear energy is the only energy that the human body does not produce.
chemical changes are only stable if the compounds themselves can coincide with another to be stable.
No, chemical changes cannot be reversed by physical changes. Chemical changes involve the formation of new substances with different properties, while physical changes only affect the state or appearance of a substance without changing its chemical composition. Once a chemical change occurs, it cannot be undone by a physical change.
This is a physical change. When the electrons go through the filament (or gas), there is no chemical change, only the physical change of temperature. The electricity to power the light may be generated chemically (fossil fuels or batteries) or from a hydroelectric plant. The light from "glow sticks" is an example of light generated by chemical changes.
