Fill in the following blanks with suitable words :
Air is a _________ conductor of heat whereas copper is a __________ conductor of heat.

Explanation

To fill in the blanks in the sentence "Air is a _________ conductor of heat whereas copper is a __________ conductor of heat," we need to consider the thermal conductivity of air and copper.

1. **Understanding Conductors**:
- Conductors are materials that allow heat to pass through them easily.
- There are good conductors (which allow heat to pass through easily) and bad conductors (which do not allow heat to pass through easily).

2. **Analyzing Air**:
- Air is known to be a poor conductor of heat. This means that it does not transfer heat well.
