A glowing splint placed in a test tube causes a loud pop Is this chemical or physical change?
Its a chemical change because a gas is produced (which is one of the signs of chemical reaction)
Are glow sticks radioactive?
No. They generate light by a process of chemical luminescence and contain no radioactive materials.
Does temperature affect the chemical reactions in glow sticks or light sticks?
Apparently if you put them in the freezer they will last longer and you can reuse them. tried it once it did light up again but not very brightly.
What are inside glow sticks?
Inside a glow stick, there is a liquid chemical, which could be glowing only once.
Are glow sticks made of the element Neon?
No, inside them a chemical reaction takes place, creating light.
Is peninsula a chemical change or physical change?

Yes it is a phisycal change because even though you cut the carrot in half its still a carrot. You're not changing the substence you are just changing what it looks like no cutting carrotis not a physical change no cutting carrotis not a physical change
Is the generation of light by an electric lamp a chemical or physical change?
This is a physical change. When the electrons go through the filament (or gas), there is no chemical change, only the physical change of temperature. The electricity to power the light may be generated chemically (fossil fuels or batteries) or from a hydroelectric plant. The light from "glow sticks" is an example of light generated by chemical changes.

Is evaporation of rubbing alcohol from your hand a physical or chemical change?
This isn't a simple "yes" or "no" question. Rubbing your hands together is not in itself a chemical change (it's not really a physical change either... it's a physical action, which is not quite the same thing). However, complicated chemical changes are required in your muscles in order to cause it to happen.

Glow sticks do not "capture" light. The light is produced by a chemical reaction. See the related link for a more in-depth discussion.
What two energy transformations happen when you rub two sticks together and fire is started?
When you rub the sticks together, you convert kinetic energy (from moving the sticks) to internal energy, or heat energy - the sticks will warm up. When the heat energy is sufficient to overcome the activation energy of the combustion (activation energy = minimum amount of energy required to start a chemical reaction), the chemical energy in the sticks/whatever you are combusting is converted to heat and light energy
