Air is quite a reasonable conductor of sound, of radio waves, and of radiant heat. It is not a good conductor of say, electricity, because of the lack of free electrons, which are needed for electrical conduction.

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 dry air a bad conductor of electricity?
Yes
Give an experiment to show that air a bad conductor of heat?
horrible
Is air a good conductor of electric charge?
Under some circumstances such as presences of the quantity of gases present in air some times air acts as good&bad conductor of electricity.
Why is air considered as a poor conductor of heat?
because u can't feel it

How is plastic foam is a poor conductor of thermal energy?
they have a very large amount of air present in them, plastic is a bad conductor

Is air a good conductor or bad conductor and why?
Air is not a conductor of electricity if it conducts electricity we cannot live. And if there is any ions present then only that can conducts electricity but air is a mixture of gases. So it is not a conductor. Lightning is proof that air is a conductor, however it is not a 'good' conductor it is about average. Air conductivity changes with moisture (humidity)and temperature level. The higher the moisture in the air, the higher its conductivity. Yes it is the water in the air that conducts generally, but the question was not "is oxygen / nitrogen / methane / etc" a good conductor. Our "Air" or "Atmosphere" is made up of a great number of components. "Paschen's Law" is what covers this question, and is pretty complex being "V=(a(pd))/(ln(pc)+b) - see link below).
How does air a bad conductor of heat help in winter?
Foam material makes good insulation.
Is air a conductor or?
Conductor
If air is considered as a poor conductor of heat why is it then you have to use insulator in handling hot materials?
When you pick up a hot item there is no air to insulate your hand.
Which is bad conductor of electricity but good conductor of heat?
glass, ceramic,diamond, are somtricitytte of the conductor of hear but bad conductor of electricity meher n sethna
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.
