Topic: Half a term paper
July 21, 2019 / By Emylynn Question:
I have noticed that if you rip paper in half while holding it in front of a dark surface, you may observe a wispy, white vapor sort of thing from the tear. I know the chemical makeup of the paper does not change. Is this simply very fine particles being released from the paper ripping or is it something else? It almost looks like smoke from a very small flame. Just curious as to the term for it.

yes, this is a common phenomenion. You will find this occurring with cloth, wood, and many substances including metal of all things. These are particles, atoms, or molecules which are set free and impelled with the mechanical destrucvtion . In the case of metals this is usually free electrons, ions, or atoms which of course cannot be seen withj the eye.
