Take a metal cylinder, and place a spring in the bottom (as a shock absorber).
Inside the metal cylinder, sitting atop the spring is a glass bottle.
Between the cylinder and the bottle (around the sides and the bottom of the glass bottle) is a vacuum. Both the vacuum and the glass serve as insulators for anything that is to be stored in the glass bottle.
This means that, if you store something warm in the inner glass bottle, it will be very difficult for the heat to conduct through the glass AND the vacuum...and the material will stay warm.
If you store something cold in the bottle, it will be very difficult for heat to conduct through the cylinder, the vacuum, and the glass...and the material will stay cold.

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.
How does thermoflask work?
Thermos Flask is a container that is used to prolong the temperature of a liquid. If a liquid it is hot,the thermos flask will work to make it stay hot longer. The heat will have no way to escape the flask which means the heat will stat longer, causing the liquid to stay hot longer.
How big is the biggest thermos flask?
The largest thermos flask ever made is a giant model created by a company called Thermos in 2014, measuring 2.2 meters (7.2 feet) tall and holding approximately 1,000 liters (about 264 gallons) of liquid. This oversized flask was designed to demonstrate the insulation capabilities of their products. In general, typical commercial thermos flasks range from small personal sizes to larger ones around 2-3 liters.
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
Why does the outer walls of thermos flask made shining?
The outer walls of a thermos flask are often made shiny for aesthetic purposes, making the flask look more appealing. Additionally, the shiny surface can help with heat reflection, reducing heat transfer between the flask and its surroundings, thus improving the overall insulation properties of the thermos.
Why do the inner surface of thermos flask kept shiny?
The shiny inner surface of a thermos flask helps to reflect heat back into the flask, reducing heat transfer to or from the contents. This helps to maintain the temperature of the liquid inside the flask for a longer period of time.
What is the thermo flask?
Thermos flask is a thermos container used to store liquids like any hot drink. The liquid added to thermos flask will retain the temperature even after some time irrespective of external temperatures.
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 do you spell thermus?
The spelling is "thermos" (still a trademark name Thermos), a vacuum-insulated flask.
