Question

air trapped in wool acts like an insulator or not​

Answer 1

Answer:yes

Explanation:warm air is bad insulator

Answer 2

Answer:

Explanation:

The fibers trap air and air is a good insulator because it doesn't allow heat to transfer through it very easily.

All materials are said to have a property called thermal conductivity which is to say that they can absorb and transfer heat with the their surroundings either very well or very badly.  

This is because different materials absorb heat differently (as a result of the bonds in their atoms and molecules). The overall effect culminates in different conductivity of heat of different materials, and air is very good at keeping heat from moving around. Thick duvets and blankets have a lot of air in them, hence they are warm and Cozy inside.
