Both result in "new" substances (ash, smoke, rust).
Burning, rusting, and production of gas are examples of chemical changes.
something rusting, something burning. chemical changes can fool you because most of the time they change color and such. but if two substances mix to make a new substance than that is a chemical change.
no rusting iron is not a physical change it is a chemical change
Ah, what a lovely question. When a bicycle rusts, it's actually a chemical change taking place. The metal is reacting with oxygen and moisture in the air, creating a new substance called iron oxide. It's all part of nature's way of transforming things, just like how we transform a blank canvas into a beautiful painting.

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.
Yes, rusting is a chemical change.
1.burning a piece of paper 2.water evaporation 3.milk goes sour 4.match is lit 5.rusting of screws
melting any metal is physical. rusting iron is chemical
A nail rusting is a chemical change. The chemical formula of the metal completely changes, adding oxygen to the formula. Iron changes from Fe to FeO2 , or to Fe2O3
Rusting is a chemical change.
A nail rusting is a chemical change.
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.
Boiling does not involve a chemical change in property. Boiling is a physical change in which a substance changes from a liquid to a gas without changing its chemical composition. The other options (rusting, burning, fermenting) involve chemical reactions that result in changes to the chemical composition of the substances involved.
The process described involves a chemical change. Boiling is a physical change as it involves a substance changing state from liquid to gas. Rusting, fermenting, and burning are chemical changes as they involve rearrangement of atoms in the substances leading to new chemical properties.
