A thermos is a container that will keep beverages hot.
No, a thermos uses insulation to minimize heat transfer through conduction, convection, and radiation. This helps to keep hot liquids hot and cold liquids cold by reducing the rate of heat exchange between the contents and the surrounding environment.
To keep a thermos hot, pre-heat the thermos with boiling water before adding the hot liquid. For cold beverages, pre-chill the thermos with cold water or ice cubes. Keep the lid tightly closed to maintain the temperature inside.

If you look inside of a thermos you will see metal. This absorbs the heat or the cold and keeps it that way for as long as the contents are in the thermos.
Fill the thermos with hot water and let it sit for a few minutes to warm up the interior. After that, pour out the hot water and immediately fill the thermos with your desired hot liquid, such as soup or coffee. This will help to keep your beverage hotter for longer.
