Metals are inorganic, they don't decompose. They might change form by bonding with other elements (e.g. rusting) but metals don't "decompose".
Sheet metal can take hundreds to thousands of years to decay, depending on factors such as the environment and the type of metal.
it depends on the person
Depends on which metal. Also, it depends on what you mean by degrade. The metal molecules will never disappear, they will just disperse or get incorporated into molecules. But in general, a LONG TIME.
To take advantage of leverage.
The time it takes for rust to eat through metal depends on various factors such as the type of metal, the environment it is exposed to, and the thickness of the metal. In general, it can take several months to years for rust to significantly eat through metal.
It depends on the orthodontist. Mine took about 30 minutes
put ya pedal to the metal. And take a good dose of sleeping pills.
If exposed to the elements, minutes.
The time it takes to melt a metal with a butane lighter will vary depending on the type of metal and the intensity of the heat produced by the lighter. Generally, it would take a significant amount of time and may not be practical to melt metal with just a butane lighter.
The answer depends on many factors:type of metal and its specific heat capacityquantity of metal in questioncurrent metal temperaturecurrent ambient temperatureDepending on these factors the answer could range from mere moments to hours or even days.
Metal is not elude. It will take a while for metal to burn.
In order to extract a metal from its mineral you need to have some solubility of that mineral, otherwise it will take too long. Let's say 2% solubility looks as a rational minimum
