To set about eating a thermos flask you would first need to recognise what the flask is made of. The simplest thermos will have an inside layer of glass, surrounded by air, surrounded by an outside layer of glass, with both these layers covered in Mercury or something similar, and the whole thing covered in plastic or metal.
The first step in eating the flask would be to separate all these layers. Heavy tools will help to smash the glass and mercury and remove them from the tougher outer casing.
Glass can be broken down and eaten pretty easily. Some people have a party trick of eating lightbulbs or wine bottles, and they can do this because it won't actually cut your mouth like you think it would. So long as you chew in a slow, controlled fashion, and use your tongue to adjust any pieces that feel sharp against your mouth, you should be able to eat the glass pretty easily.
The mercury should also be pretty easy, as the layer will be thin and crumple up with little effort. This layer is also probably poisonous, so it is recommended you leave eating the mercury til last.
The outer casing will provide the biggest problem, as it will be made of a robust material that cannot be easily chewed or digested. If it is plastic, then a particularly strong grater will be able to prepare it for eating as a condiment on your usual meals. If it is metal, then you will need to ask a local blacksmith or anyone who works with hard machinery to reduce the metal into filings which can be used in much the same way.
out of steel
inside a thermos is flask steel materials, it keeps the thermos for about 1 - 2 days.
A Thermos.
Thermos flask or vacuum flask.
Yes. The thermos flask can reduce the amount of heat travelling from the surroundings to the cold water
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.
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.
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.
The spelling is "thermos" (still a trademark name Thermos), a vacuum-insulated flask.
A vacuum is maintained in a thermos flask in order to prevent heat transfer by conduction and convection. The absence of air molecules in the vacuum reduces the amount of heat that can be transferred through these processes, helping to keep the contents of the flask hot or cold for longer periods of time.
Conduction in a thermos flask is minimized through the use of a vacuum layer between two walls of the flask. This vacuum layer prevents heat transfer by conduction, as there are no molecules present to transfer the heat. This helps to keep the contents of the flask hot or cold for an extended period of time.
A thermos flask minimizes heat transfer through conduction by having a vacuum insulated wall, which reduces heat loss. Additionally, the inner surface of the flask is reflective to prevent radiant heat loss. The space between the inner and outer walls of the thermos flask also prevents convective heat transfer by eliminating air movement.
