glow stick temperature lab
How does temperature affect a glow stick?
Increasing temperature typically increases the rate of the chemical reaction. Increasing temperature speeds up the motion of molecules, so they are more likely to bump into each other and react. In the case of glow sticks, this means a hotter temperature will make the glow stick glow more brightly.
How do you do a glow stick experiment?
Conduct the experiment. Note what time it is, in case you want to time how long each glow stick lasts. Place one stick in the cold water, one in the hot water, and leave the other at room temperature. If you like, use a thermometer to record the three temperatures. Take data. Note how brightly each tube glows. Are they all the same brightness?
What is stored energy in glow sticks?
Stored energy is called potential energy. Glow sticks contain potential energy in the form of chemicals: fluorescent dyes and a chemical called hydrogen peroxide. No light can be released until the chemicals are mixed together.
How do you know if a glow stick is exothermic?
Measure the temperature of a glow stick before activating it. Measure the temperature once you crack the stick to start the chemical reaction. If the temperature increases, the reaction is exothermic. If it decreases, it's endothermic. If you can't record a change, then the reaction is essentially neutral as far as thermal energy is concerned.

How to Do The Glow Stick Experiment
Yes, you can just activate the glow sticks, put them in the glasses, and see what happens, but that wouldn't be an experiment. Apply the scientific method: 1. Make observations. Activate the three glow sticks by snapping them to break the container inside the tube and allowing the chemicals to mix. Does the temperature of the tube change when it st
Glow Sticks and The Rate of Chemical Reaction
A glow stick is an example of chemiluminescence. This means luminescence or light is produced as the result of a chemical reaction. Several factors affect the rateof a chemical reaction, including temperature, concentration of reactants, and the presence of other chemicals. Spoiler alert: This section tells you what happened and why. Increasing tem
Are Glow Sticks Endothermic Or exothermic?
Another experiment you can perform is to determine whether or not glow sticks are endothermic or exothermic. In other words, does the chemical reaction in a glow stick absorb heat (endothermic) or release heat (exothermic)? It's also possible the chemical reaction neither absorbs nor releases heat. You might assume that a glow stick releases heat b
