Why does a thermos keep your soup hot when it's cold outside?
Most times its because there is no air in between the outside layer of the thermos and the inside layer of the thermos.
How do you heat a thermos?
I put hot water in the thermos and let sit for a few minutes until inside gets hot.
How does a thermos flask reduce conduction?
There is air between the inside and outside of the flask.
Why does water inside a thermos flask gets cooled after few days?
This is due to insulation. Inside of the Thermos the liquid remains its placed temperature longer due to the insulating either stopping heat from reaching the fluid, or by stopping heat from leaving the fluid.
Vacuum is mantained in thermos flask?
The vacuum reduce heat loss by conduction and convection.
What is inside a thermos?
inside a thermos is flask steel materials, it keeps the thermos for about 1 - 2 days.
What is the inside of a 1930's thermos made from?
The inside of a 1930 thermos was made primarily from iron with a thin coating of silver.
How does a Thermos keeps drink warm?
Thermos are double walled containers. Between each wall, the space is vaccuum sealed, so there are no air particles. This decreases the transfer of energy (by convection) from inside the warm drink to outside in the atmosphere. The second way your thermos keeps your drink warm is the shiny surface inside your thermos. Photons carrying energy bounce off the shiny surface inside the thermos, keeping high energy photons around the infrared wavelength inside the thermos. Next time you drink from your thermos, think science!

What Materials should you use to build a thermos?
no idea :( i need to know too
What is the job of a thermos?
To keep hot liquids hot and cold liquids cold by minimizing heat transfer between the inside of the thermos with the outside.
What is the principal behind a thermos flask works?
the thermal conductivity of certain materials (e.g air)is low. This makes exchange of heat between the inside and the surroundings difficult, thus allowing temperature to be mantained.
In terms of molecules moving how a does a thermos bottle keep hot liquids hot and colds liquids cold?
If you look inside of a thermos you will see metal. This absorbs the heat or the cold and keeps it that way for as long as the contents are in the thermos.
Why is the inside of a thermos flask silver?
To reduce heat loss by thermal radiation.
What material is used inside the thermos that looks silver?
It essentially a mirror on the early versions.
You own a Thermos ice bucket model 1969 The inside has become cracked Is there a fix for this problem?
If anyone knows the value of this thermos I would also be interested to know as well.
