There is no energy transformation without energy source. It is that the energy source is not battery.

Glow-sticks utilize a chemical energy to generate light so it had internal energy source.

Phosphorescence or Glow in the dark stored light energy in the form of electron state and re-emitted the light later. Energy is stored in the molecule and thus its' molecule is the energy source.

Why do glow-in-the-dark things stop glowing after some time?

When things that are supposed to glow in the dark don't, it is usually because they were not exposed to other sources of light. For example, glow stars only glow if the light in the room they decorate has been on for sometime, in a kind of absorbtion process. Without previous contact with a light source they can't glow.


Is a glow in the dark ball luminous or illuminated?

A glow in the dark ball is considered luminescent because it emits light through a chemical reaction or energy absorption rather than being illuminated by an external light source.

Does the glow in the dark z flex actually glow in the dark?

Yes, the Glow in the Dark Z Flex board is designed to emit light in the dark after being exposed to light sources. It can glow for a period of time before the energy gradually diminishes.


how does a glow glow in the dark and what makes it glow?

Glow in the dark items contain phosphors, which are materials that store light energy when exposed to light. When the lights are turned off, the phosphors slowly release this stored energy as visible light, creating the glowing effect.


Why does a glow in the dark sticker glows?

Glow in the dark stickers contain phosphorescent pigments that absorb and store light energy when exposed to light. When in a dark environment, these pigments slowly release the stored energy as visible light, creating the glowing effect.


Is a glow sticks reaction endergonic or exergonic?

The reaction in a glow stick is exergonic because it releases energy in the form of light. The chemical reaction between the two chemicals in the glow stick results in the emission of light without requiring an external source of energy.


How will the green coloured object will look in a black room?

The green-colored object will appear dark and almost invisible in a black room, as it will not reflect or absorb much light without any light source to illuminate it. The lack of contrast between the object and the room will make it difficult to see.


Does splat glow in the dark glow anytime you are not in direct light?

No, glow-in-the-dark items, including splat glob, need to be charged under direct light to emit a glowing effect in the dark. The glow will fade over time as the stored light energy diminishes.


Can you make glow in the dark slime without borax?

Yes, you can make glow in the dark slime without borax by using alternate ingredients like liquid starch or glue mixed with contact lens solution and baking soda. You can also use glow in the dark paint or powder to make the slime glow.


Do glow sticks require batteries?

No. They include their energy source, to glow for a while (thanks to a chemical reaction).


How do glow in the dark silicone bracelets work?

Glow-in-the-dark silicone bracelets are made with phosphorescent materials that absorb and store light energy when exposed to light. When in the dark, they slowly release this stored light energy in the form of a dim glow. The process is called phosphorescence.
