A quilt feels warm because the air trapped in the cotton or woolen batting acts as an insulator and does not allow the heat of the body to escape. However, when the quilt gets old - the cotton/wool gets compressed and the airspace are done away with. It does not remain as good an insulator to heat as it was earlier. Hence it feels less warm.
Yes it is
A quilt has several layers while a blanket has only one.
a potato is not an heat insulator because it's skin,but if you take the skin off it will be a heat insulator
it is good heat insulator, as it has air in it. as air is a good insulator of heat, the sponge, which has lots of pockets of air also becomes a good insulator
insulator
An insulator. More specifically, a thermal (heat) insulator, as opposed to an electrical insulator, which suppresses the flow of electricity.
a good insulator of heat keeps the heat in, so you stay warm
insulator is a object that is not a good conductorSo it keeps the heat in.
. A insulator is an element in the genetic code.
a good insulator of heat keeps the heat in, so you stay warm
an ideal thermal insulator does not conduct heat at all,so it keeps heat out!
