Question

2. A loose woollen cloth keeps us warm in winter because : ​

Answer 1

Answer:

Here we have asked the reason due to which woollen clothes keep us warm, so we will discuss here the conductivity of heat of the woollen. A material can conduct or transfer the heat through them, although it varies from material-to material. A good conductor of heat can transfer the heat easily while a poor conductor acts like an insulator and it won’t allow to transfer heat.

Explanation:

Woollen fabrics basically trap air between them and air is a poor conductor of heat. So the heat which is radiated from the body also gets trapped due to the air between the woollen fabrics which doesn’t allow it to transfer the heat in the surrounding. We can also say that the woollen fabric is also a poor conductor of heat due to which it doesn’t allow the heat to transfer into the surrounding.
