Answer 1

Answer:

A thermos flask is a special type of vessel which keeps hot liquids 'hot and cold liquids .cold' for a long time.  It reduces the loss of heat by

conduction, convection and radiation. It consists

of a double-walled glass bottle

which is a bad conductor of heat. All the air is evacuated between

the space among the two walls of the glass bottle to prevent the transfer of

heat  by conduction and convection. It is a known fact that in a vacuum, conduction  and convection cannot take place.​
