Answer 2

Answer:

3

Explanation:

Glass has a resistivity of about 1014 Ωm. Glass is usually produced when a molten material cools very fast, not allowing for enough time to pass for a regular crystal lattice to form. Common glass is mostly made up of the same chemical compound as quartz. Glass is transparent to visible light.
