Copper does not rust. It will, on contact with the air, form a greenish "verdigris" of copper sulphate on it's surface - but that is not rust.
OOps - that should be copper carbonate. Copper sulphate is highly soluble and would not produce a patina. Maybe some copper oxide as well.
A plastic toothbrush can take hundreds of years to decompose, as it is not easily broken down by natural processes. Biodegradable toothbrushes made from materials like bamboo can decompose within a few months to a few years, depending on the specific material and conditions.
The amount of time it takes for a paperclip to decompose depends on the material it is made out of. Metal paperclips take longer to decompose than plastic ones.
A regular wooden pencil can take up to 30 years to decompose in a landfill due to the slow degradation of wood and graphite. However, in an ideal composting environment, it can break down faster within a few months to a year.
Some objects decompose faster than others due to factors such as their chemical composition, exposure to moisture, temperature, and presence of microorganisms or enzymes that break down the material. Objects made of natural materials like paper and food waste decompose faster than synthetic materials like plastic, which can take hundreds of years to decompose.
Glass can take up to 1 million years to decompose in the environment, as it is not biodegradable. However, glass can be recycled indefinitely, which helps to reduce the environmental impact of its long decomposition time.
5 hours
A steel can takes about 50-100 years to decompose in the environment. However, it is important to recycle steel cans to reduce waste and conserve resources.
Does not decompose
1700 years to decompose
how lond does it take to decompose a band aid
iron does not decompose but after a long time and i mean a long time it just starts to flake away but does not decompose
it takes over a year for it to decompose
it takes about 10 years to decompose .
A cotton bag will take a few months to biodegrade/decompose.
Synthetic fabrics, such as polyester and nylon, can take hundreds to thousands of years to decompose in a landfill site due to their non-biodegradable nature. This long decomposition time contributes to environmental pollution and sustainability issues.
Fiber glass may take a very long to decompose depending on its composition. If it is pure glass or made from sand then it may never decompose.
