Is a glow stick that produces light a chemical change?
Yes, a glow stick produces light by means of a chemical change.
Is breaking a stick of gum a physical or chemical change?
Breaking a stick of gum is a physical change because the gum still retains its chemical composition even after it has been broken into smaller pieces. The breaking process only affects the physical properties of the gum, such as its shape and size, but does not change its chemical composition.
Why breaking of stick is physical change?
Breaking a stick is a physical change because the fundamental chemical composition of the stick remains the same. The physical state of the stick changes from a whole stick to smaller pieces, but the individual molecules in the stick remain unchanged.
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 breaking a glow stick a chemical or physical change?
It's a chemical change--there's a glass ampule in the glow stick. and it's got one chemical in it. Around it is another chemical. When you break the glow stick the two chemicals mix, and the glow happens.

Is the reaction inside a light stick an endothermic?
No, the reaction inside a light stick is exothermic. It involves the breaking of chemical bonds in the reactants, releasing energy in the form of light.
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.
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 breaking a stick a physical change?
YES. It surely is NOT chemical but a physical change.If you think of the stick in terms of it is a solid, then you will understand that the broken parts have not changed their physical state, only their appearance.So its physical stateis not changed, but its (mechanical, or outer properties) form is changed by force.
What evidence is there that a glowstick works as a result of a chemical change?
You may have wondered what happens when you snap a glow stick to activate it; by doing this, you're actually kicking off a chemical process that eventually leads to the production of the coloured light. Glow sticks actually contain two separate compartments, with two different chemical solutions. On a final note, glow stick reactions, like many chemical processes, can be influenced by temperature. Warmer temperatures will accelerate the rate of reaction, whilst cooler temperatures will decrease it. Want to make your glow sticks last longer? Stick them in the freezer!
What type of energy is used for a glow stick?
Chemical energy is used in a glow stick to produce light. It is a result of a chemical reaction between the substances in the glow stick that releases energy in the form of light.
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.
