Refrigerator
conduction i think
A evaporator
Cold packs, for bruises are one invention.
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.
conductor
by inhibiting heat conduction
It obsorbs the heat of the suns harmful rays.
To keep hot liquids hot and cold liquids cold by minimizing heat transfer between the inside of the thermos with the outside.

high heat capcity of the surrounding water obsorbs or releases heat energy.

Your gums will be sensitive, so be carefull with hot and cold liquids.
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.
conductor
When gasses lose heat they condense into liquids.
