Why is a rag a better conductor of heat when wet than when dry?
A dry rag has quite a bit of air trapped in its structure, and air is an insulator of heat. Replace the air with water, which conducts heat much better than air does, and the heat conductivity will be greatly increased.
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 air a poor conductor of thermal energy?
It depends what you are comparing it to, if for instance you compare it to a vaccuum then it is an infinitely better conductor. Compared to copper however it is very poor, because obviously air is a mixture of various gasses and gasses are mostly empty space; because transferal of heat is through one particle passing on energy to another through vibrations it stands to reason that the less particles you have in a set volume the less efficiently it will transfer heat.
Why put argon gas in windows?
Argon is a poor conductor of heat compared to air, it makes the window a better insulator.
What appliances uses the property of air being a bad conductor of heat?
Double glazed windows contain a layer of air between two glass windows. As air is a poor conductor of heat so the heat loss through windows is minimized. Cavity wall employs polystyrene foam that traps a large amount of air in it. As air is a poor conductor of heat so the heat loss through the walls is minimized.
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.
Why air is poor conductor of heat?
air is poor conductor of heat because we can,t feel

Why does the ground get warm during the day?
It absorbs the heat from the sun, it is a better conductor of heat than the air so it remains warm longer.
Is air a conduction?
Air is a good conductor of sound, and a poor conductor of heat and electric current.

Is Nitrogen a conductor or insulator of heat?
Yes, because it makes up 80% of the air, and air conducts heat.
Why put argon gas in windows?
Argon is a poor conductor of heat compared to air, it makes the window a better insulator.
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.

Is air a poor heat conductor?
yes air is a ploppy long jobby
