Question

on halloween, you take a glow stick, crack the capsule inside and shake it until it glows. this is an example of light energy being transformed from which type of energy? a chemical b mechanical c solution d thermal

Explanation:

A glow stick works through a chemical reaction. When the capsule is cracked, two chemicals mix. This chemical reaction releases energy in the form of light. Mechanical energy (from shaking) just helps mix the chemicals but the energy transformation to light is from chemical energy. Solution is not a form of energy. Thermal energy is related to heat, which is not the case here as glow sticks don't produce significant heat.

Answer:

A. chemical
