HOTS Questions | Heat | How Does A Thermos Flask Work?

Vacuum Flask or Thermos is an insulating storage vessel that greatly lengthens the time over which its contents remain hotter or cooler than the surroundings of the flask. But, how does a thermos flask work?

Instead of containing any kind of heating or cooling element, so as to keep hot things hot and cold things cold a thermos is designed to in a such a way that it minimizes transfer of heat by not allowing heat to escape or enter easily.

I never used thermos flasks until recently, so I wasn't informed very well about their features. I always thought they are a bit better in keeping the heat (like 30 minutes longer than normal plastic bottles etc.) by using different material. Was really impressed when I read that they can keep warm drinks warm for several hours thanks to the vacuum.

DID YOU KNOW…..
The inventor passed away prior to his work being a success.
He was granted a posthermous award.

I am amazed by the technology. I notice the coffee mug actually gets cooler to touch when it is filled with hot liquid! I wonder why that is!

Who ever is reading have a great day and everything is fine if u have problems or stressed

[neelambandhaiya]

Very good explanation, but I have one question.
The walls that are silvered are inner walls or outer walls of the inner flask.

Hi, thank u for this video! Although a silly doubt, why does the flask lose its efficiency to function over time?

[volts_yt]

I wanted something for school project I noted some points and now I am very confident.
Thank you 😁

And I am your new sub ☺

Just sitting on the porch drinking coffee and thought g I know the thermos has the walls but why does it work so well, well now I know lol

Flask water bottle are great! My cold water lasted 8 hours.
Without ice even!

My great great great grandpa's science textbook says the first rule of thermodynamics is "the darkies work during the day, and rest at night when the sun goes down." ¡Such a fucked up text book!

Is there a way to repair heat loss? I dropped my flask then the body conducted the heat.

[xondeez]

that means that i just had shitty thermos because it never seemed to work for me as a kid. it barely held heat
