Question

in the thermos flask there is a vacuum between two glass tube what is the importance of the vacuum from the following

Answer 1

We have the vacuum situated in the two glass tube of the thermos flask because the heat travels in the form of energy in the flask.

It usually travels in the form of conduction, convection, and radiation.

Because the flask is designed in this way the flash keep the items filled in the container warm

Answer 2

The Vacuum's importance is the prevention of the "conduction and convection".

Explanation:

• In the thermos flask there is a vacuum between two glass tube what is the importance of the vacuum from the following, like no transfer of heat leading to conduction and convection process.
• Hence, no heat tranfer occurs which resulting in no radiation, conduction and covection. The vacuum is the dust free area.
• The movement of object cannot be restricted due to dust free and air free.
• Once air free, it has nothing to do with mass, conduction and convection, Since there is no medium for heat conduction.
