Classify the following materials into good conductors of heat and poor conductors of heat (or insulators) : Wood, Plastic, Copper, Air, Paper, Glass, Stainless steel, Aluminium, Thermocol, Rubber.

Explanation

To classify the materials into good conductors of heat and poor conductors of heat (or insulators), we can follow these steps:

### Step 1: Understand the definitions
- **Good Conductors of Heat**: Materials that allow heat to pass through them easily. These are typically metals.
- **Poor Conductors of Heat (Insulators)**: Materials that do not allow heat to pass through them easily. These are usually non-metals or gases.

### Step 2: List the materials
The materials given in the question are:
