Take a metal cylinder, and place a spring in the bottom (as a shock absorber).
Inside the metal cylinder, sitting atop the spring is a glass bottle.
Between the cylinder and the bottle (around the sides and the bottom of the glass bottle) is a vacuum. Both the vacuum and the glass serve as insulators for anything that is to be stored in the glass bottle.
This means that, if you store something warm in the inner glass bottle, it will be very difficult for the heat to conduct through the glass AND the vacuum...and the material will stay warm.
If you store something cold in the bottle, it will be very difficult for heat to conduct through the cylinder, the vacuum, and the glass...and the material will stay cold.

What is a thermos flask made of?
out of steel
What is inside a thermos?
inside a thermos is flask steel materials, it keeps the thermos for about 1 - 2 days.
Vacuum is mantained in thermos flask?
The vacuum reduce heat loss by conduction and convection.
What is the other name for a vacuum flask?
A Thermos.
How does thermoflask work?
Thermos Flask is a container that is used to prolong the temperature of a liquid. If a liquid it is hot,the thermos flask will work to make it stay hot longer. The heat will have no way to escape the flask which means the heat will stat longer, causing the liquid to stay hot longer.
What is the thermo flask?
Thermos flask is a thermos container used to store liquids like any hot drink. The liquid added to thermos flask will retain the temperature even after some time irrespective of external temperatures.
What do you call the object that keeps water hot for hours?
Thermos flask or vacuum flask.
Is a thermos flask also good for keeping water cold for several hours?
Yes. The thermos flask can reduce the amount of heat travelling from the surroundings to the cold water
What Are Some Objects That Minimize Heat Transfer?
The vacuum flask otherwise known as a thermos flask
How does a thermos flask reduce conduction?
There is air between the inside and outside of the flask.
What is flask and how is it used?
A flask is basically a thermos that is used to hold liquids (beverages) that are meant to be kept warm.
How a thermos flask minimizes energy losses from convection?
As the flask is closed air tight, no convection current is possible.
