No. It is actually a good insulator.no
No, it's not, though it's better than you might think if you equate polystyrene with Styrofoam. Styrofoam is made of polystyrene, but it's the trapped air that makes it such a good insulator.
Air is a relatively-very-poor electrical conductor. If it were any good as a conductor,then you would need to keep your spare batteries in vacuum containers, to preventtheir becoming discharged through the air between their terminals.
air can become a good conductor when it is heated to very high temperatures
Vacuum is a good radiation conductor, and on a good day, the sunshine feels warm. Air is less good, but still a fair conductor.
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.
Ceramics are good insulators. They keep heat well because they have a lot of air trapped in them.
No, it is not.

Air is a good conductor of sound, and a poor conductor of heat and electric current.

cork, the air inside the cork isolates. (air when trapped inside a vesicle is a great isolator)

No, oxygen is not a conductor of electricity because its in the air.

Under some circumstances such as presences of the quantity of gases present in air some times air acts as good&bad conductor of electricity.
Trapped air makes a good insulator.
