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.

Rusting of an iron pole is a chemical change because it involves a chemical reaction between iron, oxygen, and water to form iron oxide (rust). This change is not reversible by physical means, such as melting or dissolving, which are characteristics of physical changes.

Why is support pole in my basement rusting even though the basement's completely dry?
Even if the basement is dry, the support pole may still be exposed to moisture in the air, causing it to rust over time. Additionally, if the support pole is in contact with the ground, it may be absorbing moisture from the soil, contributing to the rusting process. Regular maintenance and applying rust-resistant coatings can help prevent further rusting.
Is the geographic North Pole is also called the magnetic North Pole?
no, the magnetic north pole is determined by the molten iron core, and changes.
Why does the north pole of a compass point towards the earth's north magnetic pole?
The center of the earth has iron core
What is a metal pole made from?
A 'metal pole' could be made out of so many different types of metal, but most likely the metals you are looking for are Iron, Steel or a Chrome-plated pole.
Why rusting of an iron pole is not a physical change?
Because for iron to turn to rust, it must react with oxygen, which is a chemical change.

Which pole of a magnet is attracted to iron?
Any of the two poles will work. It will induce magnetism in the iron.
What is the full form of ICDP switches?
iron clad double pole switch
Does south and iron attract or repel?
South and iron attract each other. The south pole of a magnet attracts the north-seeking pole of iron, which is why a compass needle, often made of iron, aligns with the Earth's magnetic field pointing towards the North Pole.
A magnet attracts a piece of iron and the iron can then attract another piece of iron .What is the basis of this attraction?
This attraction is due to the magnetic properties of the iron material. Iron contains magnetic domains that align in the presence of a magnetic field, creating a magnetic force that attracts other magnetic materials. This is why the iron is able to be attracted by the magnet and can then itself act as a magnet to attract other pieces of iron.
Which metal became negative pole a)iron and zinc b) copper and iron c) silver and magnesium?
The correct option for the combination where one metal becomes the negative pole is: b) copper and iron
Is bending a metal pole a physical of chemical change?
Bending a metal pole is a physical change because the chemical makeup of the metal remains the same before and after bending. The arrangement of the metal atoms may change, but the metal itself is not chemically altered.
Who can participate in pole vault?
Anybody with a heart can pole-vault but it takes courage and a decent amount of physical ability(be coordinated)
Will a iron axe attract to the south pole of a magnet?
Yes, iron is a ferromagnetic material so it will be attracted to both the north and south poles of a magnet.
Is the geographic North Pole is also called the magnetic North Pole?
no, the magnetic north pole is determined by the molten iron core, and changes.
