The formation of water drops on the outside of a glass is a physical change. This occurs due to condensation, where water vapor in the air cools and changes into liquid water when it comes into contact with the cold surface of the glass. The process is reversible, as the water can evaporate back into vapor when the temperature rises. Therefore, it does not alter the chemical composition of the water.
a physical change is a phase change, such as water to ice or water vapor. a chemical change takes place on a molecular level, producing a new substance.

there are two different rates that evolution could occur at. the first kind is gradual, which is small changes over time. the other kind is fast and it occurs when there is a big change the environment.
