What else can I help you with?
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.
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 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.
Vacuum is mantained in thermos 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.
What the conduction in thermos flask?
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.
How does a thermos flask keep things hot using conduction and convestion?
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.
