If walking out side in the cold temps how would a thermos keep a drink hot compared to an open a new closed system?

There's a vacuum between the inner and outer walls of the thermos that acts as insulaion preventing the transfer of heat.

Step away from the bong dude and try again.
THERMOS - a container that keeps a drink or other fluid hot or cold by means of a double wall enclosing a vacuum.
