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.
Rusting typically requires the presence of oxygen in the gas phase, as this initiates the oxidation reaction that leads to the formation of rust. Additionally, moisture or water is also needed for the process of rusting to occur, as it helps accelerate the oxidation of the metal.
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.
The two necessary conditions for cracking to take place are high temperature and presence of a catalyst. High temperature allows for the breaking of chemical bonds in the hydrocarbon molecules, while the catalyst accelerates the cracking reaction by providing an alternative pathway with lower activation energy.
The amount of energy needed for a reaction to take place is called the activation energy. It is the minimum amount of energy required for the reactants to transform into products. This energy is needed to break bonds in the reactant molecules before new bonds can be formed.
The time it takes for a needle to rust can vary depending on the environment. In a humid or damp environment, a needle can begin to rust within hours or days. However, in a dry environment, it may take weeks or even months for a needle to start rusting.
Water and oxygen are needed.
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.
Air and water.
i dont know go ask your mom!
The five essential conditions needed for photosynthesis to take place are sunlight, carbon dioxide, water, chlorophyll, and enzymes. Without any of these conditions, photosynthesis cannot occur effectively.
Under most conditions aluminum will not rust in water. However, if the aluminum is alloyed with another metal, oxidation (rusting) could take place.
all water must be moved from the body,little to no decomposition from bacterial action can take place
heavy rainfall with flat gradient, deforested land with no drainage system.
Rusting occurs when iron or steel comes into contact with oxygen and water. This leads to a chemical reaction where the iron in the metal oxidizes to form iron oxide, also known as rust. Rusting is accelerated by factors such as salt, acid, and humidity in the environment.
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.
Rusting is the process of formation of Iron Oxides on meatls most commonly Iron. Rusting can only take place in presence of three things : IRon , Water , and Air or Oxygen. If even one of these is absent rusting cannot occur.
