water boiling
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.
Melting is an example of a physical change because it does not change the chemical composition of the substance undergoing the change. Tarnishing, rusting, and burning are examples of chemical change because they are caused by chemical reactions, which change the chemical composition of the substances undergoing the change.
Melting! A physical change would be to change something from Solid <--> Liquid <--> Gas
Water boiling is a physical process; also dissolving. Rusting is a chemical process (oxidation).

Boiling of water
boiling is a physical change. rest are chemical changes
- reactivity - flammability - aptitude to explode - electronegativity - pH - corrosion - polymerization - thermal stability - solubility - oxidation aptitude

Something that tarnishes goes through a chemical change versus a physical change.
Physical - Breaking of glass Boiling of water Melting of ice Cutting of vegetables Chemical - Burning of paper Cooking of food Rusting of iron Souring milk
