it will probably take at least 5 minutes for a needle to rust unless it is copper.
Copper does not rust; it develops a greenish film called patina when exposed to air and moisture. The formation of patina can take several years, depending on the environmental conditions.
The time it takes for something to rust depends on various factors such as the type of metal, exposure to moisture and oxygen, and environmental conditions. In general, rusting can occur in a matter of days or weeks for some metals, while others may take longer to show signs of rust.
Iron fillings can start to rust or oxidize in a matter of hours or days, depending on the humidity levels and presence of oxygen in the environment. The process of rusting occurs when iron reacts with oxygen and water, forming iron oxide.
Yes, iron can rust in water. When iron is exposed to both water and oxygen, a chemical reaction occurs where the iron oxidizes, forming iron oxide or rust. This process is accelerated in the presence of impurities in the water, such as salts and minerals.
The time it takes for screws to rust can vary depending on factors such as the type of metal used, exposure to moisture or corrosive materials, and environmental conditions. In general, low-quality screws may start to show signs of rust within a few weeks to a few months, while higher quality, rust-resistant screws may take longer to rust. Regular maintenance and protection can help prolong the lifespan of screws.
If they are an alloy, they will eventually rust.
