In the winter season, two thin blankets placed one over the other provide better insulation than a single blanket of the combined thickness because:
- 1A single thick blanket directly absorbs more heat energy from our body, cooling it down
- 2The layer of air trapped between them acts as an insulator, reducing heat loss from the body✓
- 3The air trapped between the two layers acts as an efficient thermal conductor
- 4The air trapped between the two layers absorbs extra heat energy from the surrounding atmosphere
Correct answer
The layer of air trapped between them acts as an insulator, reducing heat loss from the body
