A thermos bottle is designed to prevent heat transfer by all three modes of heat transfer: conduction, convection, and radiation. The shiny interior of a thermos bottle helps to prevent radiant heat transfer.
Radiant heat transfer occurs when heat energy is transferred through space from one object to another object without any physical contact. The shiny interior of a thermos bottle reflects radiant heat back into the bottle, preventing it from escaping or entering the bottle.
In addition to the shiny interior, a thermos bottle also has a vacuum layer between the inner and outer walls of the bottle. This vacuum layer prevents heat transfer by conduction and convection. Conduction occurs when heat energy is transferred through physical contact between two objects. The vacuum layer prevents physical contact between the inner and outer walls of the bottle, thus preventing heat transfer by conduction. Convection occurs when heat energy is transferred through the movement of fluids or gases. The vacuum layer also prevents fluid or gas movement, thus preventing heat transfer by convection.
In summary, a thermos bottle prevents all three modes of heat transfer: conduction, convection, and radiation. The shiny interior helps to prevent radiant heat transfer.
