How Thermos Work
A thermos doesn’t give heat room for heat transfer by any of the three ways including convection, conduction, and radiation, which heat can travel. It is the silver coating located on the internal surface of the thermos that puts a stop to heat transfer by radiation, while the vacuum connecting its double wall avoids heat moving by convection.
The thinness of the glass walls prevents heat from leaving or entering the thermos by conduction. Furthermore, the casing surrounding the thermos flask offers added insulation. What about radiation?
As soon as infrared radiation makes an effort to disappear from the hot liquid, the reflective lining of the inner chamber returns it back in again instantly. As a matter of fact, there is practically no way heat can break out from a thermos and a hot drink stored inside will remain steaming hot for several hours.
