When copper is exposed to moist air for a long time, it acquires a dull green coating. The green material is a mixture of copper hydroxide and copper carbonate. This film called 'verdigris' protects the underlying metal from further damage.
2Cu + H2O+CO2 + O2 Cu(OH)2 + CuCO3
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.
what will happens to a plant exposed to air
When liquid is exposed to air, it tends to evaporate. This happens because the molecules are in constant motion, and from time to time, a molecule achieves sufficient energy to overcome the atmospheric pressure above the liquid, and it escapes as a vapor.
When timber is exposed to heat, it can lose moisture, causing it to shrink and crack. Prolonged exposure to high temperatures can also weaken the structural integrity of the timber, making it more prone to deformation or collapse. In extreme cases, timber can catch fire and burn.
Nothing happens when circuit breakers are exposed to sunlight. They still work just as they are supposed to work.

Hyperthermia can set in, which is when your body is exposed to heat for a prolonged period of time, which raises the core temperature of the body. This can cause dizziness, change in blood pressure, and possible fainting.
As altitude increases, atmospheric pressure decreases.
