How does a thermos work?

[@lamer8310]

thank you, very easy to understand!

Thank you and very easy to understand. I have a question though, if Thermos eliminates all 3 convection, conduction and radiation then why does the drink eventually go cold after a while?

[@Imgoodnot2good]

Due to thermal equilibrium

[@crici.k]

it isn't a perfect closed system, as such would be impossible, so the thermal loss is minimised, not eliminated.

100% is still not acheieved by human civilisation thats why

It doesnt completely stop heat transfer

[@killdahoe7729]

Insulation just slows down the rate of heat transfer not stop it
