Answer 3

[AI-generated answer — Explain Bot]

Plastic is an example of an amorphous solid.

To understand this, let's break down the options:
- Crystalline solid: Crystalline solids have a highly ordered, repeating molecular structure, like salt or diamonds. Plastic does not have this highly ordered structure, so it's not a crystalline solid.
- High viscosity liquid: High viscosity liquids have a thick, sluggish flow, like honey or syrup. While some plastics can be melted and have a viscous flow, plastic in its solid form does not have the characteristics of a liquid.
- Fluid: Fluids refer to substances that can flow, like liquids or gases. Plastic, in its solid form, does not flow like a liquid, so it is not a fluid.
- Amorphous solid: Amorphous solids lack a regular, repeating pattern in their molecular structure, unlike crystalline solids. Plastic is formed by cooling a molten polymer, which results in a random arrangement of polymer chains, giving it an amorphous structure. Therefore, plastic is categorised as an amorphous solid.

So, the correct answer is "amorphous solid".
