the thermos works by the material that is used in them, for instance if you add something hot to it, the material becomes hot and retains the heat keeping the beverage hot. the same goes for adding something cold to a thermos , the material retains the cold and keeps the beverage cold. hope this answers your question.

It knows one thing: keep the thermos from changing temperature inside by surrounding it with insulating air.

Insulation. It prevents the transfer of heat. Keps the cold cold by limiting the transfer from the outside.

It doesen't. It reduces heat transfer in either direction. So it seems to work for both hot and cold.
