A thermos (for lack of a better word) does not "know" whether something should be hot or cold. Rather, the materials used to make a thermos are chosen to prevent heat from escaping the container (to keep the contents hot) or to prevent heat from entering the container (to keep contents cold).
Heat isn't the only thing containers are built to keep in or out: pressure is another. A thermos is merely one type of container designed to delay entropy; just as nature hates a vacuum, nature seeks to equalize temperature and pressure.
Technically, a bottle of coke, a propane cylinder and a rocket are all thermoses. This also shows why pressure and temperature are related. At high pressures, water can stay liquid as high as 180º celsius (356º fahrenheit). And it's why liquid oxygen (LOX) is used to power rockets: the release point on the container combined with ignition creates thrust.

And by calling it a "dumb" question, "Jack Skellington" shows just how dumb he is. He must be a cretin - oops, creationist - who never took a science class in his miserable life.

A thermos is quite a wormhole to a various planet, the place they do huge tests on the beverages that come and determine whether or no longer it is going to be warm. They then save it on the excellent suited temperature, till somebody opens the thermos. while somebody opens the thermos, they deliver the liquid returned to the thermos. yet each so often some thing happens while they deliver the liquid returned and it finally ends up as some thing diverse then what you put in. A classic occasion of this could be a liquid starting to be mould. A minor flaw of their transportation equipment basically differences the temperature.

the thermos is simply an insulator it attempts to maintain the temperature of the liquid you put in it.

Too funny! Another thing to ponder: How does the water know to go to the bathroom or kitchen?

It doesn't... the material just keeps heat from flowing out, and also heat from flowing in... so the liquid inside will keep its temperature for longer

does a thermos have a brain?
