A glow stick
An example of energy transformation from chemical to electric is in a battery. In a battery, chemical energy stored in the electrodes is converted into electrical energy when the circuit is completed and electrons flow from the anode to the cathode, creating an electrical current.
A chemical change is a transformation where substances are converted into different kinds of matter with new properties. This involves the rearrangement of atoms and the formation of new chemical bonds. An example of this is when hydrogen and oxygen combine to form water.
The polymerization process is an example.
A match burning is an example of chemical energy transitioning to light and heat energy.
One example of a chemical change that food goes through while eating it is the breakdown of carbohydrates into glucose during digestion. Enzymes in the digestive system help break down complex carbohydrates into simpler sugars that can be absorbed and used by the body for energy. This process involves the chemical transformation of molecules in food into different compounds that the body can utilize.

For example melting, boiling, evaporation, transformation in powder are not signs of a chemical reaction.
Water evaporating from a puddle is an example of a physical change, specifically the transformation of liquid water into water vapor. This process involves a change in state from liquid to gas without altering the chemical composition of the water molecules.
A match burning is an example of chemical energy transitioning to light and heat energy.
Without heat in an energy transformation process, the efficiency of the transformation may decrease, and some energy may be lost as unusable heat. Heat plays a crucial role in many energy conversions, helping to drive chemical reactions or provide thermal energy for mechanical work. Therefore, a lack of heat could hinder the effectiveness of the transformation process.
The rusting of iron is a chemical change that involves oxygen. When iron reacts with oxygen in the presence of water, iron oxide (rust) is formed. This process is an example of oxidation.
