Why a vacuum between a panes is better than air?
How would you fit a vacuum between window apnes :) Jokes aside, neither heat nor cold can pass through a vacuum, so you can't lose or gain heat. There's nothing there to transport the thermal energy, whereas in air, there is.
Why is vacuum created between the two walls of the flask?
A vacuum is created between the walls of a flask to minimize heat transfer through conduction or convection. Without air or gas molecules between the walls to transfer heat, the vacuum helps to maintain the temperature of the liquid inside the flask for a longer period of time.
Does germanium conduct heat?
Yes, germanium does conduct heat. It is a semiconductor material that can conduct both heat and electricity, although not as efficiently as metals. Germanium is commonly used in electronics and thermal imaging devices due to its ability to conduct heat.
Why is a vacuum a better insulator than air?
A vacuum is a better insulator than air because it lacks particles to conduct heat through conduction or convection. Without particles present, heat transfer is limited to radiation, which is less efficient. This makes vacuums good insulators for maintaining temperature, as they prevent heat loss or gain.
Is heat energy can be stored in vacuum?
No, heat energy cannot be stored in a vacuum because vacuum is an absence of matter that could hold or transfer heat. Heat needs matter to transfer through conduction, convection, or radiation. In a vacuum, there is no medium for heat transfer to occur.
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.
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
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.
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.

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.

Is outer space a conductor of heat?
Outer space is mostly a vacuum and does not conduct heat well because it lacks a medium for heat transfer to occur. In the absence of matter to carry thermal energy, heat transfer in space primarily occurs through radiation.
