Rust, scientifically known as oxidation, is a chemical change.
Rust (oxidation of metal) is a chemical change but it is also a physical change in the strength of the material.
Water boiling is a physical process; also dissolving. Rusting is a chemical process (oxidation).
Rusting is a chemical process, an oxidation reaction.
Rusting is an oxidation reaction.
Both are examples of oxidation.
Rusting is the oxidation of a metal and is an example of a chemical change.
They are all oxidation. Burning is much faster than the other two and releases large quantities of heat. Rusting and tarnishing are much slower. Tarnishing typically shows a change in color and very little in the way of physical change. Rusting slowly eats away the material as it combines with the oxygen.
In some ways. Rusting is an oxidation reaction similar to fire and it does release heat, but it is so slow that the heat does not affect the reaction. In a fire the heat released goes helps sustain the reaction.
Rusting is a chemical change because under it iron goes under oxidation and oxidation is a chemical process. Also, a physical change can be reversed but a chemical change cannot and rusting cannot be reversed. Hence also rusting is a chemical change.
A good example of an oxidation reaction. The rusting of steel is essentially just rusting (oxidation) of iron.
Rust, scientifically known as oxidation, is a chemical change.
Rust (oxidation of metal) is a chemical change but it is also a physical change in the strength of the material.
Both rusting and burning are forms of oxidation reactions. In both processes, a material combines with oxygen to form new compounds. Rusting typically involves the corrosion of metals, while burning is the combustion of organic materials, resulting in the release of heat and light.
Rust (oxidation of metal) is a chemical change but it is also a physical change in the strength of the material.
Water boiling is a physical process; also dissolving. Rusting is a chemical process (oxidation).
Freezing of water and evaporation of gasoline are physical changes because they involve a change in physical state without altering the chemical composition of the substances. Rusting of a nail is a chemical change as it involves a chemical reaction between the iron in the nail and oxygen in the air to form iron oxide.
