How Does A Thermos Work Using Conduction. Convection is heat transfer due to motion of a fluid (liquid or gas). First, the plastic in the foam is not a very good heat conductor. To keep water hot the flask must stop heat loss by conduction, convection and radiation. The substance to be kept hot or cold is kept inside a container with. Insulation works by two principles. A thermos blocks the movement of heat to and from the substance by minimizing conduction, convection, and radiation. Overall, the thermos flask works on the principle of minimizing heat transfer through a combination of vacuum insulation and reflective coating. Hotter fluids become less dense and rise up, while colder fluids become more dense and go down. Second, the air trapped in the foam is an even worse heat conductor. A vacuum flask has the following features: Creating a vacuum between the two bottles would deter heat flow through convection, and applying a reflective material to the interior bottle would deter heat from escaping through radiation. It effectively prevents heat from entering or escaping the flask, allowing the contents to retain their temperature for hours on end. Basically, stopping heat from escaping through all three known methods would mean that hot liquid would remain hot.
