Oxygen, sun, salt, water and heat.
Oxygen is very well known for speeding up the rusting of iron.
To slow down rusting of iron it is usually coated with copper metal.
This is called galvanized metal.
Salt and water, especially if both are present. Also, heat can have an accelerating effect on the rusting process.
electrolyte accelerate rusting process
Oxygen gas (O2) and water (H2O)
no its chemical. physical changes is where the object chemical matter is not altered. ex- cuting a piece of paper is physical because you still have a piece of paper but burning the paper is chemical because a chemical change has taken place.
Boiling is a physical process.
The process is called rusting.
No. Combustion is where something burns. Rusting is an example of oxidisation. ------------------ Yes, rusting is an example of slow combustion. And yes it is an oxidation reaction too, as Combustion is an oxidation reaction with an evolution of heat and/or light. In rudting there is: 1. Relase of energy. 2. Oxidation Hence, rusting is considered an oxidation reaction.
No; it is not combustion because in combustion substance react with oxygen first but in rusting the substance react with hydrogen first
Water. Salt accelerates the process. To stop things rusting keep it dry of use paint or grease.
Yes, it is correct.
Rusting is an irreversible process.
No, iron rusting is oxidation process
Stress in iron (and generally in metals and alloys) facilitates and accelerates rusting.See the links below.
Oxidation
Check
Most of the metals will oxidize, but the only one for which that process is called "rusting" is iron.
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.
Water boiling is a physical process; also dissolving. Rusting is a chemical process (oxidation).
