A glow stick is a plastic tube that contains two separate liquids. When the liquids are mixed, they glow. The diagrams show the process that causes a glow stick to emit light.

Question

Based on the diagrams, what energy transformations occur when using a glow stick?
A.

Chemical energy cracks the inner tube, which starts a reaction that transforms thermal energy into light energy.

B.

Thermal energy cracks the inner tube, which starts a reaction that transforms potential energy into light energy.

C.

Mechanical energy cracks the inner tube, which starts a reaction that transforms chemical energy into light energy.

D.

Potential energy cracks the inner tube, which starts a reaction that transforms mechanical energy into light energy.

Answer 1

The correct answer based on the information provided is:

C. Mechanical energy cracks the inner tube, which starts a reaction that transforms chemical energy into light energy.

This option accurately describes the process of breaking the inner tube of the glow stick, which involves mechanical energy, and then the chemical reaction that occurs when the two liquids mix produces light energy.
