Question

Why are quilts filled with fluffy cotton?


Open in App
Solution

Explanation:

  1. Fluffy cotton is used to fill quilts because cotton fibers have fine pores that trap air.
  2. Cotton and air are insulators of heat.
  3. They prevent heat from leaving our bodies and thus keep us warm.
  4. Because there is no air trapped in the cotton in old quilts, the newly made quilts are warmer than the old ones.
