Question

It is warmer to have two thin blankets than to have single thick blanket because:

• A. Thick blankets cannot give more warmth
• B. Two blankets allow more heat to pass through them
• C. Air between the two blankets is a good conductor of heat
• D. Air between the thin blankets does not allow heat to pass through it since it is a bad conductor

Answer 1

The correct option is D Air between the thin blankets does not allow heat to pass through it since it is a bad conductor

Air trapped between two thin blankets does not allow heat to pass through it, as air is a bad conductor of heat. Hence, it is warmer to have two thin blankets than to have a single thick blanket.
