What is the principle of a thermos flask?
If you call it by its correct name "vacuum flask" the principle becomes clear. The flask consists of an inner and outer chamber, the space between the chambers is a vacuum. A vacuum cannot conduct heat, hence no losses between the two chambers.

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.
What is a thermos flask made of?
out of steel
What is inside a thermos?
inside a thermos is flask steel materials, it keeps the thermos for about 1 - 2 days.
Vacuum is mantained in thermos flask?
The vacuum reduce heat loss by conduction and convection.
What is the other name for a vacuum flask?
A Thermos.
What do you call the object that keeps water hot for hours?
Thermos flask or vacuum flask.
Is a thermos flask also good for keeping water cold for several hours?
Yes. The thermos flask can reduce the amount of heat travelling from the surroundings to the cold water
What Are Some Objects That Minimize Heat Transfer?
Objects that minimize heat transfer are typically good insulators. This includes materials like wood, wool, fiberglass, and Styrofoam. These materials have low thermal conductivity, meaning they are less effective at conducting heat compared to materials like metal or glass.
How does a thermos flask reduce conduction?
A thermos flask reduces conduction by having a vacuum-sealed space between the inner and outer layers of the flask. This vacuum eliminates air, which is a poor conductor of heat, preventing heat loss or gain through conduction. Additionally, the inner walls of the flask are often coated with a reflective material to further minimize heat transfer by radiation.
What is flask and how is it used?
A flask is basically a thermos that is used to hold liquids (beverages) that are meant to be kept warm.
What is the thermo flask?
A thermos flask is a container designed to keep beverages, such as hot coffee or cold water, at a consistent temperature for an extended period of time. It is typically insulated with materials like glass, stainless steel, or plastic to reduce heat transfer. This allows for the retention of the beverage's original temperature, making it convenient for travel or outdoor activities.
What is the main cause of heat loss in a normal thermos flask?
The main heat loss in a good thermos flask, is due to heat conducted through the material. (Glass or Stainless Steel). There should be little heat lost through the vacuum of the flask.
How a thermos flask minimizes energy losses from convection?
As the flask is closed air tight, no convection current is possible.
