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.
water boiling
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
1 Burning of paper in the air. 2 Dissolving calcium in water 3 Slaking of Lime 4 Tanishing of silver when exposed to air 5 Clotting of blood in a wound.
A substance decomposes as a result of chemical changes in it such as rusting, tarnishing, decaying with exposure to air and affect of micro-organisms etc.

Rusting and tarnishing are examples of slow oxidation, where the naturally occurring oxygen bonds with the metal. Oxidation is a form of corrosion, since oxidation removes solid matter.
I donβt know the answer
Three chemical properties are reactivity, flammability, and oxidation state.
Its just rusting and burning.
