substances cool as they lose heat energy, and get warmer as they gain heat energy.
A thermos is an insulated container which opposes the movement of heat, thus hot liquids lose heat to the cooler outside more slowly and stay hotter for longer and cold liquids gain heat from the outside more slowly and stay colder for longer.
