Yes it is, as I tested this by using cotton to insulate drink cans which had boiling water in them. I recorded the temperatures every 2 minutes (I also tested denim and polyster. I used an uninsulated can as a control) I graphed the results on a graph and found it was a good insulator when it was both wet and dry. I tested it with denim and paper towels and cottonballs were the better insulator.
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.
It is a good insulator. Thanks please vote!!
Other answer
Cotton is a good insulator because it is soft for the ears and it also has air bubbles or air particles (airy material) that absorb sound.
Other good materials are polystyrene/foam, rubber and plastic :) Hope I helped <3
Yes, if they're dry. Cotton balls are made up of small little individual fibers which have air surrounding each one. These are small air pockets, which reduce heat caused by conduction or convection. When cotton balls are wet, they do the opposite because the air pockets are filled with water, which is denser than air, making it transfer heat more readily.
Hope this helped.
wool is the best insulator
Yes
no
Dry cotton holds air still. Dead air space (not moving) is the best natural insulator.
No, cotton is not a better insulator than aluminum foil and tissue paper. Aluminum foil is a good insulator as it reflects heat, while tissue paper acts as a thermal barrier. Cotton, on the other hand, is not as effective of an insulator because it does not have the same reflective or thermal barrier properties.
insulator
cotton
It is a insulator since it is not metal
semi conductor
cotton wool
cotton wool
Yes.
Cotton keeps its heat very well.
As a substance with electrostatic properties amber must be an insulator.
Cotton wool is not a conductor or an insulator it is a semi conductor. It is sort of in the middle, electrons can travel through cotton wool but not as good as silver, bronze, metal and so on.
