Why is cotton-wool a good insulator?

Answer 1

It has lots of air trapped between its fibres. Air itself is a good insulator, so trapped air is going to prevent heat transfer.

Cotton is a very good insulator as long as it stays dry. There are thousands of tiny air spaces between the fibers that slow the transmission of heat or cold. That is why jackets or even T-shirts feel like good protection from the cold when outside.

Answer 2

Well, honey, cotton-wool is a good insulator because it traps air between its fibers, creating a barrier that slows down the transfer of heat. It's like wearing a cozy sweater in the winter - keeps you warm by keeping the heat close to your body. So, next time you're freezing your butt off, just remember that cotton-wool is there to save the day.

Answer 3

Oh, dude, like, cotton-wool is a great insulator because it traps air between its fibers, creating a barrier against heat transfer. It's like wearing a cozy sweater in the winter - keeps you warm by keeping that precious heat close to your body. So yeah, cotton-wool is basically the MVP of insulation, keeping things toasty without breaking a sweat.

Answer 4

Cotton wool is a good insulator due to its structure and composition. The fibers in cotton wool create air pockets that trap heat, preventing it from easily escaping. Additionally, cotton wool is a poor conductor of heat, meaning it does not transfer heat well. This combination of factors makes cotton wool an effective insulator for maintaining warmth in various applications.

Answer 5

Cotton-wool is a good insulator because it traps air within its fibers, creating pockets of air that slow down the transfer of heat. The air pockets reduce conduction and convection of heat, helping to maintain a stable temperature. Additionally, cotton-wool is a natural and breathable material that is non-allergenic and safe for use in various applications.
