Copper, over the course of time, is gradually oxidized when exposed to air. It takes quite awhile for this reaction to occur naturally; however, the reaction is expedited with heat. The result is Copper oxide.
When copper is exposed to air, it forms a layer of greenish-colored copper oxide on its surface through a process known as oxidation. This layer acts as a protective barrier, preventing further oxidation and corrosion of the underlying copper metal.
A property doesn't eact.
When a chemical change happens, a physical property is change. A physical property something that you could use to describe something or someone with your senses.
Rock exposed to very high temperature and pressure will soften or melt.
what will happens to a plant exposed to air
Chemical Weathering.. because as rocks exposed to acid rains like limestones, it slowly dissolve and change into a new form

what happens when they are exposed to water
Chemical properties describe how a substance can form new substances by undergoing chemical reactions, like flammability or reactivity. Physical properties describe characteristics that can be observed without changing the substance's identity, like color, density, or melting point.
When rust is exposed to hot water, it can accelerate the corrosion process. The heat can speed up the chemical reactions that cause rust to form, leading to faster deterioration of the metal.
Selenium is photoconductive, meaning its electrical conductivity increases when exposed to light. This property is used in applications such as photocopiers and solar cells. However, prolonged exposure to bright light can degrade selenium's performance.
They turn to stone when the are exposed in the sun
