WHY inner bottle's outer body of a thermous flask is made up of silver in colour?
The outer body of a thermos flask is often made of a silver-colored material to provide insulation and prevent heat transfer. The silver color helps in reflecting heat, maintaining the temperature inside the flask for a longer period. Additionally, the silver color gives the thermos flask a sleek and modern appearance.
Why does liquid remain hot or cold for a long time inside a thermos flask?
A thermos flask has a double-walled design with a vacuum layer in between, which minimizes heat transfer by conduction and convection. This helps prevent heat loss or gain from the liquid inside, keeping it hot or cold for a longer time. Additionally, the reflective lining inside the flask reduces heat transfer by radiation.
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.
Can a thermos flask keep cold water cold?
Yes, a thermos flask can keep cold water cold for several hours due to its insulated design that helps to maintain the temperature of the liquid inside. It is more effective at keeping beverages hot, but it can also help to preserve the cold temperature of water for a decent amount 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.
What is inside a thermos?
inside a thermos is flask steel materials, it keeps the thermos for about 1 - 2 days.

The silver color helps in reflecting heat, maintaining the temperature inside the flask for a longer period. Additionally, the silver color gives the thermos flask a sleek and modern appearance.
Why the outer body of inner bottle of thermos flask is made silver in colour?
The outer body of the inner bottle of a thermos flask is often made silver in color to provide a reflective surface. This reflective surface helps to minimize heat transfer through radiation, improving the overall insulation of the flask and allowing it to better retain the temperature of the contents inside.
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.
Why does liquid remain hot or cold for a long time inside a thermos flask?
A thermos flask has a double-walled design with a vacuum layer in between, which minimizes heat transfer by conduction and convection. This helps prevent heat loss or gain from the liquid inside, keeping it hot or cold for a longer time. Additionally, the reflective lining inside the flask reduces heat transfer by radiation.
What is a thermos flask made of?
out of steel
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.
Which mode of heat transfer is thwarted by the shiny surface in a thermos flask?
Radiation is the mode of heat transfer that is thwarted by the shiny surface in a thermos flask. The shiny surface reflects the radiant heat, preventing it from escaping the flask and helping to maintain the temperature of the contents inside for longer periods of time.
Why is the inside part of the thermos flask shiny?
It helps to insulate the thing inside the thermo flask. The heat or coldness outside the flask gets reflected away. It might sound silly but it is true
What is the other name for a vacuum flask?
A Thermos.
How does a thermos flask reduce heat loss by radiation?
Vaccum between thermos walls does NOT prevent radiation, however the other forms of heat transfer(convection and conduction) are more or less eliminated. Radiation effect of heat transfer may be reduced by applying a layer of reflective material inside the bootles - to reflect the emmision back inwards.
Why does water inside a thermos flask gets cooled after few days?
The water inside a thermos flask may cool down over a few days due to heat transfer through the walls of the flask. Even though thermos flasks are designed to keep liquids hot or cold for an extended period, they are not perfectly insulated, so gradual heat transfer can occur. Additionally, external temperature changes or opening the flask can also contribute to the cooling of the water over time.
