Question

why does wearing many layers of cotton clothes keep you warm in winter than wearing one thick sweater
please answer the question pls ​

Answer 1

Wearing more layers of cotton creates air pockets which keep us warm as woolens. Textile fibers ( sweater) differ in their ability to conduct heat but it is the thermal resistance of trapped pockets of air, not the conductivity of fiber which determines the thermal properties of textiles.

Answer 2

Answer:

because many layers of clothes don't allow cool air to pass through them whereas only one thick sweater also don't allow cool air but some time it may feel you cool
