Sponge is not a good heat insulator as it is porous and can easily transfer heat. Materials like cork or fiberglass are better heat insulators due to their low thermal conductivity.
An insulator
Platinum is a horrible insulator. Being metal, it conducts heat and electricity quite well.
Lead is a metal and is considered a good conductor of electricity. It is not a semiconductor or insulator.
A thermal insulator is designed to keep heat in or out, depending on the direction of heat flow. It reduces heat transfer by trapping air or creating a barrier that slows down the movement of heat energy.
a potato is not an heat insulator because it's skin,but if you take the skin off it will be a heat insulator
Sponge is not a good heat insulator as it is porous and can easily transfer heat. Materials like cork or fiberglass are better heat insulators due to their low thermal conductivity.
Nitrogen is not a good insulator of heat. It is a poor conductor of heat, but it is not an effective insulator as it does not trap heat well and can easily transfer heat through convection or conduction.
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
. A insulator is an element in the genetic code.
insulator is a object that is not a good conductorSo it keeps the heat in.
a good insulator of heat keeps the heat in, so you stay warm
an electrical insulator blocks the flow of electricity (like the rubber around power cords that stop you from getting electrecuted) and a heat insulator block the flow of heat (like a thermos)
vvvvvvv
probably insulator
wood is an insulator of heat because its electrons don't allow heat and electricity to flow through them
