Why is vacuum created between the two walls of the flask?
So that there is nothing to physicall conduct heat across the gap.
Does germanium conduct heat?
Germanium is a metal that does conduct heat, but does not conduct heat as well as other metals. This makes it a semiconductor.
Which meterial not conduct the heat?
Non-metals tend to not conduct heat
Why can not heat be conducted by vacuum?
No heat OR electricity can be conducted in a vacuum because of the mere fact that a vacuum has no particles in it that can vibrate to produce heat in the first place
Is it possible for heat to flow across a vacuum?
Heat needs something to "flow" through. In a vacuum it will not have a medium to travel through and so heat cannot flow across a vacuum. Radiant heat will travel through a vacuum but here it is the light energy that is passing through the vacuum, not the heat energy.
How a vacuum conducts heat?
A vacuum does NOT conduct heat !
Can heat be conduct through vacuum?
Yes, heat is an electromagnetic energy like light.
Does Lithium conduct heat?
Lithium does indeed conduct heat. All forms of matter conduct heat to a greater or lesser degree; only a vacuum has no heat conducting capacity. And even in a vacuum, heat can be radiated in the form of infrared radiation.

What things conduct heat?
Technically, everything. Any amount of matter will conduct heat as a matter of molecular vibrations. However, heat conduction increases with density and delocalization of bonds (metals are the best conductors, followed by some forms of graphite, then probably some organic molecules, then other molecules, then salts, then lastly rocks and such).
How the thermos flask prevents heat loss by conduction?
There is a dead air space between the liner of the thermos and the outside. This space acts as insulation preventing conduction. In a really good thermos, or Dewar flask, the space is actually a vacuum. Vacuum is an even better insulator than air is, since heat doesn't conduct across a vacuum at all.
Does a teapot conduct heat?
can a teapot conduct heat
What are some poor conductors of heat?
Poor conductors of heat are generally also poor conductors of electricity. These would include most gases, ceramics and man-made plastics. A vacuum will not conduct heat either.
How does the structure of a vacuum flask minimise energy transfer?
The vacuum between the two layers cannot conduct heat.The silvering on the inside reflects heat back to the contents.The stopper prevents heat loss by convection.The stopper is made of poor thermal conductors.
Does germanium conduct heat?
Germanium is a metal that does conduct heat, but does not conduct heat as well as other metals. This makes it a semiconductor.
What is the principle of a thermos flask?
If you call it by its correct name "vacuum flask" the principle becomes clear. The flask consists of an inner and outer chamber, the space between the chambers is a vacuum. A vacuum cannot conduct heat, hence no losses between the two chambers.
