No, a metal bar glowing red hot in a fire would be an example of a physical change, not a chemical change.

Is rusting a chemical property or a chemical change?
Rust its self is a chemical change, but a chemical property for a car would be that it gets rusty over time.
What are examples of chemical and physical change?
melting any metal is physical. rusting iron is chemical
Is using hot water to expand a metal cup a physical or chemical change?
Physical- the metal isn't changing. If you burned it, then perhaps it would be chemical. But it's physical.
If copper metal rusts would it be a physical change?
If you use a abrasive to scrape the rust off, then it is a physical change. If you utilize a chemical that combines with the rust leaving the unoxidized penny behind, then it is a chemical change.
Why the rusting of an iron pole is not physical change?
The rusting of an iron pole is a chemical change. An example of a chemical change would be crumbling a piece of paper. When you are crumbling this piece of paper, the contents of the paper have not change and you are able to uncrumble the paper there is no difference except the paper has wrinkles. :) However in an example of chemical change like a metal rusting, you cannot un-rust it, it was chemically changed. Another example of a chemical change would be burning a piece of paper to ashes.
Is shortening metal a physical or chemical change?
Of itself a metal can not be "shortened". However, a metal OBJECT such as a piece of metal wire can be shortened by cutting a piece off. This would be a physical change.
Is metal cooled and taken out of a mold a physical or chemical change?
This would be a physical change because there is no change in the chemical make up of the metal and there is no creation of new substances there is simply a change in state for the metal.
Is rusting a physical change of metal?
Chemical Yes. The metal is being converted to an oxide of that metal. Most would (correctly) describe this as a chemical change, but physics has a lot to do with how that happens.

Is the heating of iron III oxide for sometime a physical or chemical change?
Just heating the metal would be a physical change, as you would only have a warmer iron III oxide. However, if the heat caused a reaction, it would then be a chemical change.
Is non rusting metal a physical change?
If by non rusting you mean it is in the same state it was made in then it wouldn't be part of any change. But if something is rusting it would be a chemical change because the metal is changing composition and it is not the same metal it was in the first place.
What type of chemical change is a slow combination of a substance with oxygen?
The slow combination of a substance with oxygen is typically referred to as oxidation. This chemical change usually involves the loss of electrons from the substance, leading to the formation of new compounds. Examples include rusting of iron and browning of fruits.
Is metal rusting a chemical change?
Firstly, only iron rusts. Other metals are said to corrode, but either is a chemical change.
If copper metal rusts would it be a physical change?
If you use a abrasive to scrape the rust off, then it is a physical change. If you utilize a chemical that combines with the rust leaving the unoxidized penny behind, then it is a chemical change.
What happens in a chemical change but not in a physical change?
If you bend a paper clip it is a physical change because it is still a paper clip. It's chemical identity has not changed. In a chemical change, the chemical identity of a substance changes. For example, if the paper clip were made of steel and rusted, then it's chemical identity would change to include oxygen chemically bonded to the metal, iron oxide.
