How is conduction prevented in a thermos flask?
There are many ways this is done. It can be done by having a double walled thermos with either air, an insulator, or a vacuum between. A vacuum will prevent all conduction except where the two walls touch but requires stronger materials.
How does a thermos flask reduce conduction?
There is air between the inside and outside of the flask.
Vacuum is mantained in thermos flask?
The vacuum reduce heat loss by conduction and convection.
Why do you think the thermos bottle contains a vacuum or space from which the air has been removed?
it prevents conduction and convection the 2 main causes of heat transfer
How does a thermos flask reduce heat loss by conduction?
Using vacuum as an insulator avoids heat loss by conduction. Heat transfer is minimised by reflective silver surfaces that are applied to the flask. This prevents thermal radiation from entering and escaping the flask.
Why you create vacuum in thermos flask?
This reduces heat transport through conduction and convection.
What processes of heat transfer are affected with thermos flasks?
Conduction, convection and heat radiation.

What to take to work?
Lunch & a thermos.

The vacuum reduce heat loss by conduction and convection.
What will keep your pasta warm at school?
A thermos bottle (Actually a thermos container, which has a wider lid) will work.
What does silver layer of an insulated bottle does this to radiated heat?

How do thermos work?
A thermos works with principle of Physics that vacuum is a pure insulator of heat. Thermos is made of two containers separated by a vacuum space which acts as an insulator of heat. Also the surface of thermos will be glassy which in turn helps in reduction of heat loss.
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.
