It is a physical change of form.
Because its physical shape changes, what it is didn't change, which would be a chemical change.
It is a physical change because you did not put acid on it or something.
It's a chemical change--there's a glass ampule in the glow stick. and it's got one chemical in it. Around it is another chemical. When you break the glow stick the two chemicals mix, and the glow happens.
Breaking a light stick is not a chemical in and of its self, but the subsequent process that produces light is.
It is a physical change as there is no change chemically in the composition of the stick
YES. It surely is NOT chemical but a physical change.If you think of the stick in terms of it is a solid, then you will understand that the broken parts have not changed their physical state, only their appearance.So its physical stateis not changed, but its (mechanical, or outer properties) form is changed by force.
A light stick is a toy that shows a physical change. A light stick is broken so it will light up. The liquid inside the stick completes a chemical change.
Light sticks are chemical changes.
I don't know
physical change because it is still wood, just charred
