Question

Why are quilts filled with fluffy cotton?

Answer 1

Hint: We are asked the importance of fluffy cotton in quilts. We can start to answer this question by stating what quilts are and what their function is, and why they are used. This can lead us to our required answer as to why these quilts are filled with cotton.

Complete Step By Step Answer:
Let us start by stating what quilts are and their purpose. Quilts are multi layered clothing that is often seen with two or three layers being used. These quilts are used in order to keep one from the cold. That is, they are used to keep them warm.
When quilts are filled with fluffy cotton, air becomes trapped in them. Cotton has pores in them, the air that is trapped is actually trapped in these pores. We know that cotton and air are both insulators. This presence of two conductors (that is, air and cotton) prevents the heat already present in our bodies from leaving the body thus keeping us warm.
In conclusion, the fluffy cotton inside the quilts help to trap air and keep the body warm.

Note:
Materials can be classified into two bases on their capability to conduct heat. They are, namely, conductors and insulators.
Conductors: These are those materials that allow heat to pass through. They are also known as heat conductors. Some examples include wood, and metals like iron, aluminum etc.
Insulators: These are those materials that do not allow heat to pass through. Some examples other than air and cotton are plastic and rubber.
