Breaking a light stick chemical change?
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.
Is mixing two substances and light is produced a chemical or physical change?
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.
What if your body converts chemical energy to all of the following EXCEPT?
Nuclear energy is the only energy that the human body does not produce.
Chemical changes can be reserved by physical change?
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.
Is transparency chemical change?
Transparency is a physical property of a substance that describes how much light can pass through it. It is not a chemical change since the substance remains the same chemically, only its ability to allow light to pass through changes.
Does only the sun chemical changes produce light?
yes
Can only the sun and chemical changes produce light?
No. Any object that is hot enough will produce light, regardless of what heated it.
Breaking a light stick chemical change?
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.

Does oxygen produce light?
Essentially oxygen does not produce light ... light itself is an energy, and cannot be created only changed
What are the chemical and physical changes of photosynthesis?
There are no physical changes. there are only chemical changes.

How does the moon produce light?
The moon does not produce light. It only reflects light from the sun.
What if your body converts chemical energy to all of the following EXCEPT?
Nuclear energy is the only energy that the human body does not produce.
Why are chemical changes stable?
chemical changes are only stable if the compounds themselves can coincide with another to be stable.
Chemical changes can be reserved by physical change?
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.
Is the generation of light by an electric lamp a chemical or 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.
When is a reaction considered chemical?
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.
