What is a physical change Milk becomes sour an iron nail rusts?
A physical change refers to a change in appearance or state that does not alter the chemical composition of the substance. When milk sours, it undergoes a physical change because its appearance and taste change, but the molecules remain the same. Similarly, when an iron nail rusts, it is a physical change because the iron's appearance changes as it forms rust, but the chemical composition of the iron is not altered.
When iron rusts is that a chemical or physical change?
It is a chemical change, the iron is being oxidized and forming rust. A good way to think about it is if you can undo it then it is a physical change. For example if you put salt in water, that is a physical change because you can boil off the water and get the salt back. Source: AP Chemistry
What are the examlpes of chemical change and physical change?
Examples of chemical changes: * Burning of paper * Rusting of iron Examples of physical reactions: * Melting of ice * Melting of wax
Is iron rusting a chemical or physical change?
Iron rusting is a chemical change: oxidation of the metal by oxygen in the air or water. When iron 'rusts' it oxidises. This is a chemical change, a physical change is when a molecule changes state, for example iron melting and going from a solid to a liquid.
Is it chemical or physical change if you leave your bicycle out in the rain and it rusts?
Chemical, as rust is iron oxide. The iron is turning from iron to iron oxide, which (as you can see) is a chemical change. In general, a colour change usually indicates a chemical change.
Is iron rusts a physical or chemical change?

Is iron rusts a physical or chemical reaction?
Iron rusting is a chemical change.
Is iron nail rusts in water a chemical change or a physical change?
Chemical change, oxygen binds with iron.
How can you tell there is a chemical reaction when iron rusts?
Because it is not a physical change it is a chemical change.
Is a tin can rusts a physical or chemical change?
Yes, it is, because the chemical composition of the outside changes due to oxydation.
Is there a chemical or physical change when a bicycle rusts in the rain?
Rusting is a chemical change, as steel/iron turns into iron oxide.
Is iron that rusts in moist a physical property chemical property physical change or a chemical change?
Rusting is a chemical process, an oxidation reaction.
Is iron rusts chemical or physical?
Chemical reaction from water

Is the color of iron wire a physical or chemical change?
The color change of iron wire when it rusts is a chemical change because it involves a reaction with oxygen in the air to form iron oxide. This new substance has different properties than the original iron.
Is a bar of iron rusts a chemical change?
Yes.
