What is the difference between a thermos flask and vacuum flask?
A thermos flask has double walls, which are evacuated and the vacuum bottle is silvered on the inside.
The vacuum between the two walls prevents heat being transferred from the inside to the outside by conduction and convection..
Why vacuum flask is called thermos flask?
Vacuum flask is commonly called thermos flask because vacuum prevents conduction same with thermos flask. The tight stopper prevents air from entering or leaving the flask so there is a no chance of convention.
Can a thermos explode?
The near-vacuum that exists between the flask’s walls makes the flask somewhat prone to implosion. Stirring with an SS spoon is not recommended (although often will not actually cause a problem) because it can scratch the inside of the flask, making it even more vulnerable to implosion.
