What occurs when some materials are exposed to oxygen and water over time and can result in rusting?
Oxidation happens.
How long does it take pewter to cool?
The cooling time of pewter can vary depending on the thickness of the pewter item. Typically, pewter will cool and solidify within a few minutes to an hour. Rapid cooling techniques can also be used to speed up the process.
What happenes when liquid is 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.

Is pewter waterproof?
Pewter is not completely waterproof. It can be susceptible to corrosion and tarnishing when exposed to extended periods of moisture or harsh environmental conditions. It is important to properly care for pewter items to maintain their appearance and longevity.
What happens if pewter gets wet?
If pewter gets wet, it may develop water stains or tarnish. It is important to dry pewter thoroughly after it gets wet to prevent any damage. Additionally, prolonged exposure to water could potentially cause corrosion on the surface of pewter over time.

Is pewter biodegradable?
Yes, pewter is a naturally occurring metal alloy composed mostly of tin, which is known to be biodegradable. Over time, pewter will corrode and break down in the environment, making it environmentally friendly compared to other non-biodegradable materials.
What happens to copper's chemical property when it is exposed to air?
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.
What happens when a camera is exposed to sunlight for an extended period of time?
If it is exposed to sunlight while being in excessive heat it can damage the internals of the camera.
Do amethysts fade over time?
Yes, amethysts can fade over time when exposed to prolonged sunlight or heat.
Is it Ok for home concrete foundation wall rebar be exposed to the outside elements?
No. Exposure will allow the bar to rust. The rust will travel through the bar over time, not stay isolated to just the exposed area. Over time the rust could compromise the integrity of the bar and cause failure. As to the rate this happens, it is based of the amount of exposure and conditions it is in.
