How do molecules of the scissor blade break the bonds of the (mostly carbon?) atoms that make up paper without heat?
In: Chemistry
Firstly, it’s not breaking the molecular bonds. Secondly, there is heat in the form of friction, it’s just negligible.
Scissors work less using the laws of chemistry and more the laws of physics. It’s design allows a lot of force ie you grasp, to be exerted onto a very tiny point on the paper, this breaks the paper. As you close the scissors they continue to open this tear.
