For example thermal energy.
The enthalpy of reaction
Chemical energy is produced. Light energy is used
chemical change
chemical energy
when a chemical change occurs, chemical bonds are broken up
Plants can change light energy into chemical energy during the process of photosynthesis!
Chemical energy is produced. Actually light energy is converted
heat is produced
Physical changes are generally easy to reverse because NO ENERGY is produced by the substance.A Chemical change cannot be reversed because ENERGY is produced by the substance forming a new substance.
Yes it is released/ absorbed during chemical changes.
chemical change
A chemical change. Chemical changes can also be indicated if energy is given off. Physical changes on the other hand do not produce energy or produce new substances.
