it is a physical change
Chromatography is a physical change because even though you are separating colors the original atomic identity of the colored ink being separated is still retained showing that a chemical reaction has not taken place.
Separating rocks and dirt is a physical change because it doesn't change the identity of either substance.
no... physical
It is a physical change because it is still fountain pen ink. It wouldn't be a chemical change because it didn't change into a new substance.

No it is not a Chemical Change. It is a Physical Change.

It's Physical your just separating your not mixing chemicals and what not(:

It is a physical change because the chemical composition id not affected.
This is not a change at all. However it is physical when you use a magnet to physically seperate (by manetic force) .
chromatography
Separations of mixtures would be a physical change because you are not changing the chemical make-up of the mixture. Instead, you are simply sorting parts of the mixture. For example, taking out all of the blue blocks in a bag full of red, yellow, green, and blue blocks would be an example of a physical change and separating a mixture.
