Question

a student places a glow stick in hot water and observes it glows more brightly. why is this a result of a chemical change influenced by temperature? the light reflects off the water and the glow stick shines brighter when submerged in water. the plastic becomes clearer in hot water and which results in the chemical change being easier to observe. the glow stick melts the chemical reaction inside the glow stick speeds up with heat, releasing more energy as light

Explanation:

Glow sticks work via a chemical reaction. Temperature affects reaction rates. Higher temperature (hot water) increases the kinetic energy of reactant molecules. This leads to more frequent and energetic collisions, speeding up the chemical reaction. As a result, more energy is released as light.

Answer:

The chemical reaction inside the glow stick speeds up with heat, releasing more energy as light.
