Is breaking a glowstick exothermic

Answer 1

Exothermic is where heat/energy is released.

And a glow stick does exactly that. but in this case the energy being released is in the form of light.

Do not be fooled, a glow stick does not release heat. just energy

So yes, a glow stick IS exothermic.

Answer 2

Yes, breaking a glowstick results in a chemical reaction inside that produces light. This reaction is exothermic, meaning it releases energy in the form of heat and light.
