Is a thermos good after 20 years?

Can be, if the vacuum is good. In glass thermos if the glass is not broken it is okay. In steel thermos if the vacuum has not been lost it will be. You can test a steel thermos by simply filling it with boiling water, if the outside of the thermos becomes hot the vacuum has been lost and one will need a new thermos.


What feature of a thermos does not limit heat flow?

Vacuum insulation is a feature of a thermos that does not limit heat flow. By creating a vacuum between the inner and outer walls of the thermos, heat transfer through conduction and convection is minimized, allowing liquids to maintain their temperature for longer periods.


How and where does the most heat loss occur in a thermos bottle?

The most heat loss in a thermos bottle occurs through conduction, convection, and radiation. It mainly happens at the opening of the thermos bottle where there is direct contact with the surrounding environment, as well as through the materials used in the construction of the bottle that are not efficient insulators.


Why some thermos bottles are good for 24 hours but others are for 48 hours?
