Why is a car rusting a physical change?
no its chemical. physical changes is where the object chemical matter is not altered. ex- cuting a piece of paper is physical because you still have a piece of paper but burning the paper is chemical because a chemical change has taken place.
Is rubbing a marker on a paper a chemical reaction?
Rubbing a marker on paper does not involve a chemical reaction. The transfer of ink from the marker to the paper is a physical process, specifically the physical adhesion of the ink to the paper fibers.
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
What is a chemical reaction melting ice rubbing a marker on paper burning a candle rusting iron?
Melting ice is a physical change as it involves a change in state from solid to liquid without changing the chemical composition. Rubbing a marker on paper involves a physical process of transferring ink from the marker to the paper, without any new chemical reactions occurring. Burning a candle is a combustion reaction where the wax reacts with oxygen to produce heat, light, carbon dioxide, and water vapor. Rusting iron is a chemical process where iron reacts with oxygen and moisture in the air to form iron oxide.
Is coloring on a white piece of paper a physical change or a chemical change?
Coloring on a white piece of paper is a physical change because the color change is reversible and does not alter the chemical composition of the paper. The paper remains paper even after coloring on it.

Why the rusting of an iron pole is not a 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 tearing a paper a chemical or a physical change?
Tearing paper represents a physical and not a chemical change. Chemical bonds are not broken in this instance, but paper is physically separated (by force) from other paper.
Is cutting a paper physical or chemical change?
It is a physical change because it is still a sheet of paper.
Is a cucumber turning into a pickle a chemical or physical change?
Its a chemical change. Chemical changes produces a new substance while physical change does not Examples of physical change are ripping paper, breaking a bottle and melting ice. Examples of Chemical change are cooking macaroni, rusting iron and mixing acids and bases to make salt and water
Is a bicycle chain rusting chemical or physical water is absored by a paper towel a chemical or physical?
The rusting metal of the chain is chemical and the towel that is now wet is physical. The water is still water but the metal is now been oxidized.
What would be a physical change metal rusting silver tarnishing water boiling or paper burning?
Rusting of metal and tarnishing of silver are chemical changes because new substances are formed. Boiling water is a physical change as the water changes state from liquid to gas. Burning paper is a chemical change as the paper undergoes a combustion reaction to form new substances like ash and gases.
tearing a piece of paper in half physical or chemical change?
Physical change
Is cutting paper a chemical?
No, cutting paper is a physical change, not a chemical change. The paper's chemical composition remains the same before and after cutting; only its physical shape is altered.
