Is breaking a stick of gum a physical or chemical change?
It is a physical change of form.
Is breaking a glow stick a chemical or physical change?
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.
Why breaking of stick is physical change?
It is a physical change because you did not put acid on it or something.

can heat add energy to the chemical reaction in a glwo stick

What is a demonstration of a chemical change?
Light a match. The glob of material on the end, and later the wood/paper stick, is undergoing a chemical change.
What energy change occurs during burning a match stick?
chemical energy to light and heat energy
Is breaking a stick a physical change?
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.

When you snap a glow stick what does the snapping the tube do and how does it lead to chemical reaction?
I just had to do a project exactly on this, When you snap a glow stick a chemical change happens. A glow stick has an outer tube (the bendy one) and an inner glass tube (the one you hear cracking). By snapping a glow stick you are cracking open the inner tube which hold chemicals, the outer tube has phenyl oxalate and fluorescent dye in it, and the inner glass tube has a hydrogen peroxide solution in it. When these chemicals are released and come together, it releases energy in the form of light, thus, making a chemical change. So when you do your favorite activity with a glow stick, cracking it (admit it, it's your favorite part), you are breaking the inner glass tube, which then releases the hydrogen peroxide solution into the phenyl oxalate/dye solution, creating an enchantingly glowing stick of light! hope this was helpful! - Jessica
