The brightness of the glowstick should increase as it gets hotter since the molecules are colliding more frequently Discussion: The brightness of the glowsticks is directly proportional to the temperature; reactions get faster as they get hotter and slower as they get colder
DrHal GlowSticks
The hot water has faster moving particles than the cold and room temperature water These fast-‐ moving particles collide with the glow stick, transferring energy This causes the liquid particles in the glow stick to move quicker, increasing the rate of the chemical reaction
