evaporation, vaporization, melting, liquefaction, etc.
erosion, moon phases, seasons, global warming, ice melting
The changes produced by electrolysis are chemical.
Examples of chemical changes in nature include wood burning in a forest fire, photosynthesis, the formation of sulfuric acid in volcanic vents, and the fixing of nitrogen in lightning bolts and bacteria.
No. Nothing changes in its chemical nature.
no
The most important changes are of chemical nature; water evaporation is a physical process.
A phase change is a physical change. It is not a chemical change.
some chemical changes can be reversed but they are hard to reverse usually
Sensors of varying nature can measure the physical and chemical changes in the Environment. At present, there are no instruments that can measure both physical and chemical factors.
Freezing/melting or evaporation/condensation, are physical changes that don't affect the chemical nature of the substances.
Some chemical changes are reversible, others are not.
