Question

What are the characteristics of a substance that resembles glass?

1) Transparency
2) Hardness
3) Brittleness
4) Luster
5) Low or no porosity

Answer 1

Glass has characteristics including transparency, hardness, brittleness, luster, and low or no porosity.

Step-by-step explanation:

Glass is a non-crystalline, often transparent amorphous solid that has certain characteristics:

1. Transparency: Glass is transparent, allowing light to pass through.
2. Hardness: Glass is a hard material that can scratch other materials.
3. Brittleness: Glass is brittle, meaning it can easily break or shatter when subjected to stress.
4. Luster: Glass can have a smooth, shiny appearance.
5. Low or no porosity: Glass is generally non-porous or has very low porosity, preventing liquids or gases from permeating through.
