Question

Why does wearing more layers of clothing during winter keep us warmer than wearing just one thick piece of clothing?
[2 marks]

Answer 1

• The air gets trapped between two layers of warm clothes. (0.5 marks)
• Air acts as insulator of heat. (0.5 marks)
• This prevents our body heat to escape out to the surroundings. (0.5 marks)
• More layers of clothes will allow more air to get trapped and as a result, we will not feel cold. (0.5 marks)

So wearing more layers of clothing during winter keeps us warmer than wearing just one thick piece of clothing.
