Is glass or air a better conductor?
Glass is a better conductor of heat compared to air because it has a higher thermal conductivity. Air is a poor conductor of heat due to its low density and lower thermal conductivity.
Does air conduct heat poorly?
Air is a poor conductor of heat compared to materials like metals because it has low density and lacks a crystalline structure that allows efficient heat transfer. However, air can still transfer heat through convection, where hot air rises and cold air sinks, making it a better insulator than a conductor of heat.
Why is a blanket a better conductor of heat when it's wet rather than it being dry?
Water conducts heat better than air, so when a blanket is wet, the water content aids in transferring heat more efficiently. This is because water molecules are closer together, allowing for better heat conduction compared to air-filled dry blankets.
Is wool conductor of heat?
Wool holds lot of air. As air is a bad conductor of heat, this makes the wool a bad conductor of heat, but a good insulator.
Is a wet blanket or a dry blanket a better heat conductor?
A wet blanket is a better heat conductor than a dry blanket because water is more conductive than air. The moisture in the wet blanket helps to transfer heat more efficiently from the body to the blanket.
Which is a better conductor of heat air or a copper wire?
A copper wire is a much better conductor of heat than air is.
Is glass or air a better conductor?
Glass is a better conductor of heat compared to air because it has a higher thermal conductivity. Air is a poor conductor of heat due to its low density and lower thermal conductivity.
Why air is poor conductor of heat?
air is poor conductor of heat because we can,t feel

Is air a conduction?
Air is a good conductor of sound, and a poor conductor of heat and electric current.
Which substance is the best insulator air glass or silver?
Air is the best insulator of the three substances mentioned (air, glass, and silver) because it is a poor conductor of heat and electricity. Glass is better than silver at insulating heat due to its higher resistance to heat transfer, but both air and glass have better insulating properties than silver. Silver is a good conductor of heat and electricity, making it a poor insulator compared to air and glass.

A wet blanket is a better heat conductor than a dry blanket because water is more conductive than air. The moisture in the wet blanket helps to transfer heat more efficiently from the body to the blanket.
Is air a poor conductor of thermal energy?
Yes, air is a poor conductor of thermal energy. It is a good insulator because the molecules in air are far apart, making it difficult for heat to transfer through it. This is why air is often used as an insulating material in homes and buildings.
How is a radiator a conductor?
A radiator is a conductor because it is made of metal, which is a material that allows heat to flow through it easily. When hot water or steam passes through the radiator, the metal quickly heats up and transfers that heat to the surrounding air, helping to warm up a room.
If air would be a better heat conductor would the earth be colder or warmer during the night and why?
If air was to retain the heat from the sun during saylight hours then the earth would stay warmer for longer, however air is constantly moving so we get air from different parts of the world. so if it is cold near to the UK while they have sunlight and we have night time then we are more likely to be cold so even if air was a better heat conductor we would not be warmer during the night.
