Question

a neon light consists of a glass tube with metal wires at each end. when connected to a high-voltage source, the gas glows.

if a fly lands on the glass tube, what will most likely happen?

○ the fly will not feel a shock because the glass conducts any free electrons back into the gas.
○ electrons will flow directly from the metal wires along the glass and shock the fly.
○ the fly will not feel a shock because the glass insulates it from the electrons in the gas and the metal.
○ electrons that are moving through the gas will be conducted through the glass and shock the fly.

Explanation:

To solve this, we analyze the properties of glass (an insulator) and the neon light setup:

1. Recall that glass is an electrical insulator, meaning it does not conduct electricity well.
2. Analyze each option:

• Option 1: Glass is an insulator, not a conductor, so this is incorrect.
• Option 2: Glass does not allow electrons to flow along it, so this is incorrect.
• Option 3: Since glass insulates, the fly (on the glass) will not be shocked by electrons in the gas or metal. This matches the properties of an insulator.
• Option 4: Glass does not conduct electrons from the gas to the fly, so this is incorrect.

Answer:

The fly will not feel a shock because the glass insulates it from the electrons in the gas and the metal.
