How do single use glow sticks work?
Disposable glow sticks utilize a chemical reaction to produce their familiar green glow. A glass capsule inside the plastic tube releases a phenyl oxalate solution into the surrounding hydrogen dioxide solution, and once they are mixed well, they react with each other and produce light energy. It is possible to manipulate the color of the glow stick depending on the chemicals used.
What type of energy is used in movement?
Kinetic energy.
What type of energy is a slinky?
kenetic energy is the type that is used when it moves but it is not energy but it uses it as all things do
What is the answer to thisThe energy used to move most bicycles is an example of what type of energy?
Chemical Energy is used to move most of vehicles
What type of energy used for a heat pump?
Thermal energy is used in heat pumps. Solar energy can also be used.
What type of energy dose a light stick have?
Assuming that you are referring to non-electric light sticks, it is chemical energy. The reaction is started by mechanical energy (cracking the stick). The chemical nature of glow sticks is also evident in the fact that they die down eventually after the reactants are used up.
What is an whell in Poptropica?
a glow stick which is used to get the gold egg for the giant to get past him and get the flag A GLOW STICK
Are glow sticks made with water?
There is no water used in the making of a standard glow stick, it is simply a chemical reaction between two chemicals. Water can however be used to make a glow stick brighter.
What has to be brokn before it is used?
an egg and a glow stick
Is neon used in glow sticks?
Scientists have extracted the element neon from space and made into a "liquid neon" which they sell to neon glow stick factories, which is then put into the neon glow sticks.

Three examples of chemiluminescence?
Glows sticks are a common type of chemiluminescent. When the glass vial of hydrogen peroxide reacts with the phenyl oxalate ester (oxidizing it), a glow is produced; the color based on the fluorescent dye also in the stick. Another example is luminol, which is used in crime scene investigation do detect blood (the chemical reacts with iron in the hemoglobin). In nature, the glow from fireflies is another example of chemiluminescence.
What is praise of science and what is critical of science?
Data: The cold water was at a temperature of -8 degrees Celsius. The hot water was at 80 degrees Celsius, and the room temperature water was 23 degrees Celsius. Our observations when we put the glow stick in the cooler water, the glow sticks light intensity decreased the longer the glow stick sat there. After a much longer period of time the light of the glow stick completely went out. When we put the glow stick in the hotter water the light of the glow stick increased significantly, the color of the glow stick became a much brighter color pink. At the room temperature the glow stick in the water when we broke it the color was light but not as bright as the one in the hotter water but not as dark in the colder water, but it stayed the same as when we broke it.Conclusion: During class, we have been conducting our science fair experiment on glow sticks and there light reaction to hot, cold, and room temperature waters. We secured each glow stick in a glass of water at temperatures of 80 degrees Celsius (hot), -8 degrees Celsius (cold) and 23 degrees Celsius. (About room temperature). The environments that a glow stick is keep does affect the way the chemical reaction between the dye, ester, and hydrogen peroxide, in which how bright the energy is giving off during the reaction. Our hypothesis was; if I change the environment temperature of the glow sticks then when secured in a hotter environment the glow sticks light intensity will be brighter. This was our hypotheses because I thought if the chemicals during the reaction we heated, and the warmer the water is the faster the bonds move. It is easier and faster to mix the chemicals more quickly in result the energy of the chemical reaction would produce more light. My hypothesis was supported. When we secluded the glow stick in a hotter temperature the glow stick became much bright, and over time the glow stick even changed to lighter color pink. In some cases there could have been some errors, perhaps if the glow stick had already had the capsule broken or the glow stick was out dated, and even if the water was too cool or not cool enough. You could defiantly use this information learned in the real world. That many things that can result in chemical reactions and you can learn that the glow sticks chemical reaction, it shows the energy giving off by the glow sticks combinations of chemicals. I would like to learn more about what's in each chemical, and how each of them reacts in order to produce the light? by; sarah.+++.Well done, Sarah, and certainly science, but I am not sure how it answers the heading question! I was interested to see that the temperature seems to affect the colour as well as brightness. I have a question though: how did you keep the water liquid at -8ºC? In a formal report you would add such details so that if anyone wishes to repeat your study they can ensure they are doing so correctly..I do see that you considered if using a used or out-dated glow-stick could give errors, and error-reduction is an important part of any scientific experiment. Here is a classic example:.Have you read how the pioneering physicist, Joule (after whom the unit of energy is named) established the link between mechanical and heat energy, hence the foundation of the law that energy can only be transferred or converted? He repeated the test, using a weight-driven stirrer in a cask of water, many, many times, and tried to find and reduce the errors as much as possible, to obtain a result that was as accurate as possible. (The water is warmed slightly by being agitated, showing the mechanical energy used to rotate the paddles is converted to heat energy in the water. By very careful measurement and calculation Joule established the conversion numerically.)
Is neon used to make glow sticks?
No a glow stick contains two chemicals and a suitable fluorescent dye (sensitizer, or fluorophor). The chemicals in the glass vial are a mixture of the dye and diphenyl oxalate.
What temperature does it have to be in order for briquettes to glow?
Briquettes are a type of charcoal used when cooking on the grill. These charcoal pieces get so hot that they glow in 400 degree heat.
What is a wiener stick?
A wiener stick is a skewer-type utensil used for cooking hot dogs.
What can this type of energy be used for?
no
