Question

When we use blanket why do we feel warm?

• A. Because the blanket is warm
• B. Because the blanket doesn't allow air to enter
• C. Because our body is warm
• D. None of the above

Answer 1

The correct option is B Because the blanket doesn't allow air to enter

Cold air tries to carry body heat away. Blankets form a barrier between the body and cold air. Hence heat doesn't transfer through the blankets as air will not flow through the blankets.
