Answer 1

Answer:

• warmer underneath two blankets due to air layer between them.

Explanation:

• When we use two thin blankets with the total thickness equaling the thickness of the single thick blanket we can get better shielding from cold outside.

• There is a thin layer of air between two thin blankets. That prevents heat transfer in either direction.  Air is a good insulator. The main way of heat transfer in air is by radiation.

• In a blanket the heat is transferred by conduction.
• Further it is more convenient too to use two thin blankets. One single thick blanket is heavy, uncomfortable, and unmanageable too.
