Water and oxygen are needed.
Air and water.
in a metal when their is presence of oxygen and water rusting takes place
Rusting requires conditions such as moisture and air (oxygen).
Under most conditions aluminum will not rust in water. However, if the aluminum is alloyed with another metal, oxidation (rusting) could take place.
humidity
The conditions necessary for rusting are water (or water vapour) and air, specifically Oxygen. If one condition is absent and the other is present then rusting would not occur but if both are present then rusting will occur
Oxygen is a very important agent needed for rusting and decaying to take place. Oxygen binds with the surface and creates water while breaking down the substance.
No,because distilled water has no salts
MOISTURE AND OXYGEN
Moist and sometimes warm environment. Also only certain kinds of metals or mixes of metals rust. For example, gold doesn't rust, but iron easily rusts.
When Iron became in contact with water and oxygen or other strong oxidants or acids the rusting took place. The rusting is an electrochemical process which started with the transfer of electrons form iron to oxygen. If salt is present then it also accelerate the rusting process.
Rusting is a chemical reaction that iron undergoes involving water and oxygen. There is no pxygen or liquid water on the moon, and therefor nothing for the iron to react with.
