Hey mate!

Here's your answer!!

Thermos flask is a thermos container used to store liquids like any hot drink.A thermous flask contains only vaccum, which prevents the loss of heat of the liquid inside. The liquid added to thermos flask will retain the temperature even after some time irrespective of external temperatures.

Hi friend !!!!!

Here is your absolute amswer :

1. It consists of a double walled glass vessel and in between the walls, a vacuum is created to prevent the heat loss by conduction.

2. The inner surface and outer surface of its walls are silvered to prevent the heat loss by radiation.

3. The mouth of the bottle is fitted with an insulating stopper to prevent heat loss by convection.
