Breaking a light stick chemical change?
When you break a light stick, it is a physical change, not a chemical change. The breaking of the light stick only changes its physical state but does not alter its chemical composition. This is because the chemical reactions that produce light in a light stick have already occurred when the stick was activated, and breaking it does not initiate any new chemical reactions.
Is a glow stick chemical change?
Yes, the glow stick undergoes a chemical change when it is activated. The chemical reaction between the components inside the stick creates the light emission.
Is a glow stick endothermic or exothermic?
a glow stick can be a endothermic or exothermic reaction
Is burning of an incense stick as physical or a chemical change give reason?
Burning of an incense stick is a chemical change because it involves a chemical reaction where the compounds in the incense stick are transformed into new substances such as ash, smoke, and gases. This change is irreversible and results in the formation of different chemical compounds than those present in the original incense stick.
Are glow sticks glowing a chemical change?
Yes, the glowing of glow sticks is a chemical change. It results from a chemical reaction between the chemicals inside the stick when they are mixed, producing light as a byproduct.

Is a glow stick chemical change?
Yes, the glow stick undergoes a chemical change when it is activated. The chemical reaction between the components inside the stick creates the light emission.
What energy transfer is in a light stick?
In a light stick, the energy transfer involves converting chemical energy into light energy. A chemical reaction inside the light stick produces light without generating heat, making it a safe and efficient source of illumination.
What type of energy is released in a glow stick?
Chemical energy is released in a glow stick through a chemical reaction between the chemicals inside the stick. This reaction produces light energy in the form of visible light.
Is a light stick endothermic or exothermic?
A light stick is considered exothermic because it produces light through a chemical reaction that releases energy in the form of light and heat.
What kind of energy does the stick of a match have?
The stick of a match contains chemical energy, which is released when the match is struck, causing a chemical reaction that produces heat and light.
What type of energy transformation used in a glow stick?
Chemical energy is converted to light energy in a glow stick. When the chemicals inside the glow stick mix, a chemical reaction occurs that produces light without generating heat.
Does an incandescent bulb and a light stick use the same form of energy to create light?
No, an incandescent bulb produces light by heating a filament to a high temperature until it glows, using electrical energy. On the other hand, a light stick produces light through a chemical reaction, where two chemical compounds mix together to create light, without the need for electricity.
What type of energy is a glow Stick?
A glow stick produces light energy via a chemical reaction known as chemiluminescence. This reaction occurs when two chemicals inside the stick are mixed together.
What is a demonstration of a chemical change?
Light a match. The glob of material on the end, and later the wood/paper stick, is undergoing a chemical change.
How does glow produce light?
A glow stick produces light through a chemical reaction called chemiluminescence. This reaction occurs when two chemicals within the glow stick mix together inside the plastic casing. The mixing of these chemicals produces energy in the form of light.
What is the energy transformation for a glow stick?
In a glow stick, chemical energy is converted into light energy through a process called chemiluminescence. When the chemicals inside the glow stick are mixed, a chemical reaction occurs that produces light without emitting heat.
