Answer 1

Explanation:

The one thing that is most important for any type of heat transfer is the medium through which the heat is transferring.

So far different kind of heat transfers are happening, they are Radiation Convection or Conduction.

And each medium has certain transfer of heat requirement and lack of that medium, then the stoppage of transfer happening.

To a certain extent this phenomenon is used in thermal flask which cancel out the medium of transfer of heat, thereby keeping things warm or cold as they are.
