A flask. It also keeps drinks hot.
A thermos keeps hot drinks hot and cold drinks cold by using a vacuum layer between two walls of the container. This vacuum layer prevents heat transfer by conduction, convection, and radiation. The result is that hot drinks stay hot because heat loss is minimized, and cold drinks stay cold because heat gain is minimized.
No
A thermos will generally keep either a hot item hot or a cold item cold. you can use them for things like cold drinks, soup, hot chocolate, or pretty much any liquid you want to keep the same temperature.

yes you can
Cold is better because you can cover up to keep yourself warm whereas hot it is harder to get cooler unless you carry around a portable fan.
Usually, food is heated to a temperature hotter than the temperature of a room, about 160F. and drinks are usually much cooler than room temperature around 45F or less. So both hot food and cold drinks will eventually equal the temperature of the space or room they are left in.
You can use a cooler with ice packs or frozen gel packs to keep liquids cold while on a trip on a hot day. Make sure to seal the containers tightly and place them at the bottom of the cooler for better insulation. Avoid opening the cooler frequently to maintain the cold temperature inside.
YES! YES! YES! Tervis keeps hot drinks hot and cold drinks cold!
