Mechanical to Light
The mass of a glowstick remains the same when it lights up. The glowstick undergoes a chemical reaction that produces light, but the total mass of the components inside the glowstick does not change.
No, it is not recommended to refreeze a glowstick. Freezing and thawing a glowstick can cause it to lose its effectiveness and may damage the chemical components inside. It is safer to dispose of the glowstick properly after use.
Glowsticks use chemical energy stored within a combination of hydrogen peroxide and a phenyl oxalate ester. When the glowstick is activated by bending and breaking an inner glass vial containing the chemicals, a chemical reaction occurs that produces light energy in the form of chemiluminescence.
When a bell is rung, mechanical energy from the person ringing the bell is transferred to the bell causing it to vibrate. The vibration of the bell produces sound energy as it moves through the air, creating the ringing sound. So, the energy transformations involved are from mechanical energy to sound energy.
Putting a glowstick in the freezer will slow down the chemical reaction inside, causing it to dim or stop glowing temporarily. Once the glowstick returns to room temperature, it should glow normally again.
Kinetic energy becomes heat by way of the friction caused by braking.

yeah, just put the glowstick in the freezer, it wont glow as much but it lasts longer!

YouTube is where I found them
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 energySo yes, a glow stick IS exothermic.Hope this was helpful- Jessica
