describe the construction of the thermos flask without the help of a neat diagram and label it?
Answers
Explanation:
A thermos is a bottle with a double-walled container inside of it. The air between the two walls is sucked out during construction, creating a vacuum. Instead of containing some kind of heating element to keep hot things hot, a thermos is designed to keep hot things hot by not allowing heat to escape.
Construction:
It is constructed in such a way that heat loss due to conduction, convection, and radiation is minimized. It is a double-walled bottle of thin glass and the space between the walls is evacuated. The mouth of the bottle is closed by a cork or plastic stopper.
A thermos flask or vacuum flask is a bit like a super-insulated jug. A typical thermos has an inner glass chamber and an outer plastic one. The outer material can also be made of metal, like stainless steel, for greater durability of the flask. Between the inner and outer layers, there is a vacuum.
