What is the important of chemical changes?
A chemical change is when some thing changes into another energy or substance. It is important to make different things. A example is a piece of wood burning offers heat and light.
What are examples of chemical change caused by light energy?
Examples of chemical changes caused by light energy include photosynthesis in plants, which converts carbon dioxide and water into glucose and oxygen using light energy, and photodegradation of plastics, where light exposure breaks down the polymer chains, leading to degradation.
What is the definition of photo-chemical?
Related to or caused by the chemical action of light
Lighting a match changes chemical energy into heat and light The total amount of energy?
The total amount of energy remains constant, but it is transformed from chemical energy in the match head to thermal energy (heat) and electromagnetic energy (light) when the match is lit. This is an example of energy conservation in a closed system.

What is the name of the study of changes to materials caused by light?
The study of changes to materials caused by light is known as photodegradation or photochemistry. This field explores how light can alter the properties and structure of materials over time.
A chemical reaction that occurs in plants that changes light energy into chemical energy is?
photosynthesis
What is the chemical process that changes light energy to chemical energy?
You think probable to photosynthesis.
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.
What are all the energy changes?
There are many different ways that energy changes. For example electrical energy can transform into heat energy, cold energy or light energy. Other energies and their changes can include gravitational, chemical, mechanical and kinetic.
Is the detonation of fireworks a physical or chemical change?
The actual detonation (a rapid oxidation reaction) is an example of a chemical change.The resulting blast of expanding gas, sound, and light; and the shredding of the casings are physical changes.
What process changes light energy into chemical energy?
Photosynthesis
