Heat Transfer - Conduction, Convection, and Radiation

This physics video tutorial provides a basic introduction into heat transfer. It explains the difference between conduction, convection, and radiation. Conduction occurs when heat transfers from one material to another by direct contact. Touching a hot stove is an example of heat conduction. Heat flows from a region of high temperature to a region of low temperature or from hot to cold. Materials such as metals and diamond conduct heat very well. Wood and fiberglass do not conduct heat very well and are called insulators. still air is an insulator. Convection occurs when heat is transferred through a fluid in motion such as moving water or a wind. Hot air rises and cold air descends due to difference in density. Cold air is heavier than hot air. The last method of heat transfer is radiation. Heat from the sun travels through empty space by means of electromagnetic waves such as infrared, UV light, and visible light.

So is a down jacket a good insulator due to trapped air or the feathers? Or both.

[@mkpetersen1607]

Down is a fantastic insulator as the loft (or fluffiness) of down creates thousands of tiny air pockets which trap warm air and retain heat, thus helping to keep the wearer very warm in cold winter weather.

[@fractalnomics]

If air doesn't conduct (implying collisions) how does greenhouse theory work then? How does the atmosphere transfer heat by convection if it doesn't conduct and the non-greenhouse gases don't radiate? It is said to transfer by collisions (conduct) Something is wrong. Air must radiate.

[@smalltrashman4227]

Greenhouse theory hasn't been 100% proven so your point is moot.

[@SaadyourSavior]

I think that should be graphite instead of diamond in the place of metal conductivity.....?? cause diamond isn't much good conductor of electricity as well as heat.

[@fractalnomics]

8:12 the nitrogen and the oxygen in the air are assumed by greenhouse theory not to radiate infrared, so you can't say ' in fact every object with a temperature above absolute zero radiates' when it is assumed by greenhouse theory not to; nitrogen and oxygen get their heat only from conduction (collisions) which you have shown not to happen also. Physics has a problem and I have the solution to all this.
