First of all, cotton has air spaces in between it, so many of us may think it is a poor conductor. But actually, saw dust is a poorer conductor of heat than cotton.
CONDUCTORSilver is a conductor of heat and electricity.
Actually diamond is the best conductor of heat, and a diamond film substrate is used as a heat conductor in some microprocessors. Silver and copper are the metals more commonly used as heat conductors because of cost.
No, milk is not a good conductor.
conductor- metal (especially copper) is a great conductor of electricity. Silver is a great conductor of heat.
no it is not.
No, wood is not an efficient conductor of heat and energy compared to metals like copper or aluminum. Wood has a lower thermal conductivity, meaning it is a poorer conductor of heat and energy.
Yes sawdust is an insulator such as Wood, Plastic, Styrofoam, Rubber, Paper, Glass, Cotton, Sand, Aerogel, and Wool. Cotton and Wool is likely to be found in a sock. These insulators can stop heat or electricity from flowing through them.
Cotton is a poor conductor of heat because it is a lightweight and airy material that traps air within its fibers. Air is a poor conductor of heat, so the air pockets within cotton help to insulate and retain heat, making it a good choice for clothing in both warm and cool weather.
semi conductor
Of those two choices, wood, when it's dry, is the poorer conductor, of both electricity and heat.
It's not that it's warmer actually. What happens is that carpet is poorer at wicking heat from your body. It's a poorer conductor of heat. This means that when you touch it, the part that touches it doesn't lose almost any heat, which makes it feel warm.
its a good insulator, meaning that yes, it is a good non-conductor. Materials that insulate heat, eg wool, cotton etc, are also by definition good electrical insulators. Good conductors would include most metals, which you may have noticed are bad insulators. you wouldn't wear metal underwear anyway!
The answer is dryed air (0,024 W/m.K).
Glass tends to get cold faster than plastic because it is a better conductor of heat, allowing heat to escape more easily into the surrounding environment. Plastic is a poorer conductor of heat, so it retains heat longer and takes longer to cool down.
The answer to this question depends on the magic word NIC. NIC is short for non-intercellular. This means that the tiny cells within the foam do not connect with each other. The foam does not soak up lots of water. You can't blow air through it. A plastic foam which is NIC is a very poor conductor of heat - a good insulator. A plastic foam which is intercellular is not a good conductor, but it is nowhere near as poor as NIC foam. Its best use is as a sponge for soaking up water.
Metal is a better conductor of heat than plastic, so it transfers heat more efficiently from the hot water to the surroundings, resulting in faster cooling. Plastic, on the other hand, is a poorer conductor of heat, so it retains heat better and slows down the cooling process.
It is not a heat conductor.
