True or false every chemical or physical change in matter includes a change in energy?
Every chemical or physical change in matter includes a change in energy.
Is production of heat or light physical or chemical change?
i think it would be physical because it is still energy.
What occurs when energy is added or taken away?
When energy is added,solid will melt into liquid or liquid will change into gas. (When energy is added it gains heat).When energy is removed, the liquid will turn into solid or the gas will turn into liquid. (When energy is removed the heat will lose).
In a candle explain both changes using the big idea of energy?
When a candle is burnt a physical AND chemical change takes place. Its a physical change when the wax is being melted because the chemical structure has not change, meaning it cannot be a chemical change. Its also a chemical change because you are burning the string. When you burn something the chemical structure DOES change, meaning it is a chemical change.
Compare and contrast chemical change and physical change?
physical change is reversable while chemicle change is not and they both change because of some kind of energy that's all i can think of srry.

What can change light energy to chemical energy?
Plants can change light energy into chemical energy during the process of photosynthesis!
What happens to energy when matter undergoes chemical or physical change?
Energy can either be soaked up by the matter in the process of making the change (melting), or be released from the matter during the change (fire).
