For example melting, boiling, evaporation, transformation in powder are not signs of a chemical reaction.

Chemical Change occurs when one or more recognized substances cease to be recognizable and one or more "new" substances is now newly recognized. "Old and new" being distinguishable characteristic properties. Chemical change can be reversed; however, the reverse must also be chemical. Chemical changes are those that can be undone with "difficulty", whereas a physical change can be undone comparatively easy. For instance, if you tear a piece of paper in two, you can tape it back together. If, however, you burn the piece of paper, there is no way to get the paper back from the ash. except through photosynthesis -- it has undergone a chemical change, one which cannot be undone very easily. More examples: Physical: A balloon contracts when it is cooled A pond freezes over Gold is shaped into jewelry Salt dissolves in water A paper shredder rips paper Chemical: Food digests Silver tarnishes Vinegar reacts with baking soda to produce CO2 Wood burns An apple browns A copper church steeple turns green A candle burns
In a chemical reaction, reactants are transformed into products through the breaking and formation of chemical bonds. The sequence of events typically involves collision of reactant molecules, formation of activated complex, rearrangement of atoms to form new bonds, and ultimately the formation of products. This process follows the principles of conservation of mass and energy.
Events that destabilize or change a system are commonly referred to as "perturbations" or "disturbances." In various contexts, such as ecology, economics, or social systems, these events can also be termed "shocks" or "disruptions." They can lead to significant changes in the system's dynamics, potentially resulting in new equilibria or states. Understanding these events is crucial for analyzing system resilience and adaptability.
Extreme weather events, such as hurricanes, tornadoes, or heatwaves, can cause the most damage to the environment due to their intensity and widespread impact. These events can lead to habitat destruction, loss of biodiversity, and damage to ecosystems, affecting both wildlife and human communities.

A cyclic change is a change that happens in an orderly way and where the events repeat constantly. Cyclic changes include seasonal events and tides.
