Thermos Flask prevent loss or gain of heat by separating the internal layer and the external layer with a vacuum (absence of air molecules). Heat is usually transferred through different media (air molecules and other molecules). Without these media, heat can't pass from one place to another, except for radiation which doesn't need any media (it can travel through vacuum)

How thermos flask prevent loss or gain of heat by?
A vacuum makes a good heat insulator.
Vacuum is mantained in thermos flask?
The vacuum reduce heat loss by conduction and convection.
How does a thermos flask reduce heat loss by radiation?
Vaccum between thermos walls does NOT prevent radiation, however the other forms of heat transfer(convection and conduction) are more or less eliminated. Radiation effect of heat transfer may be reduced by applying a layer of reflective material inside the bootles - to reflect the emmision back inwards.
What Are Some Objects That Minimize Heat Transfer?
The vacuum flask otherwise known as a thermos flask
How does the mirror coating prent thermos flask lose heat?
It shiny mirrored surface reflect heat which means the heat will be reduced

What is the main cause of heat loss in a normal thermos flask?
The main heat loss in a good thermos flask, is due to heat conducted through the material. (Glass or Stainless Steel). There should be little heat lost through the vacuum of the flask.

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.
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
Why is the inside of a thermos flask silver?
To reduce heat loss by thermal radiation.
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.
How stuff works?
Thermos flask It works with a contraption in it which keeps all the heat in the bottom!
Why you create vacuum in thermos flask?
This reduces heat transport through conduction and convection.
How does the mirror coating prent thermos flask lose heat?
It shiny mirrored surface reflect heat which means the heat will be reduced
