if air is a bad conductor of heat.?

Question

why don't we feel warm in winter without clothes?explain.

Answer 1

Because hot air rises and cold air sinks - it's heavier and hense will be found more at ground level.

Answer 2

It's a relatively bad conductor. Compared to most metals and other materials it comes out low. Huge masses of cold air float in during the winter (if air was a better conductor, that air would be warmed by the next sunrise).
Our atmosphere gets pounded by (relatively) huge amounts of energy from the sun. Also the ground keeps the day's heat pretty well (which heats the air).

Answer 3

In winter our body temperature is quite high compared to
the surroundings. Hence our body continuously loses heat by radiation which is independent of medium. But When we wear clothes it contains trapped air and air being a bad conductor of heat does allow heat to escape and hence we feel warm. Now U may ask whether the body cannot lose heat by radiation when we wear clothes but yet why don't we feel cold. Here's my answer.

Heat is lost by all 3 modes conduction, convection and radiation. But when we wear clothes the air trapped between our body increases and air being a bad conductor of heat does not allow heat to escape and hence the more clothes we wear the more air is trapped and hence less heat escapes.

Got it!!!!!!!

Answer 4

The atmosphere convects heat energy to us less effiently that heat is passed by through a solid or through a liquid as the particles are more concentrated in those types of matter.

So air is not as a good onducter as most other substances. But heat can still be conveted through air quite well. So it depends on the context of your queation.

I hope this helped!

Answer 5

Its more like a burner on a stove. The air surrounding it doesn't heat up much but an iron skillet on top of it is very hot to the touch.
