Why is the inner of the thermos bottle is silvered?
because it radiates heat.
Why the outer body of inner bottle of thermos flask is made silver in colour?
because the take heat heat inside and not allowed it heat to get outside
What insulation material can keep objects cool?
A vacuum is a good insulator so a "thermos" bottle will keep liquids 8or solids) cool for a while.
Vacuum is mantained in thermos flask?
The vacuum reduce heat loss by conduction and convection.
How do thermos work?
A thermos works with principle of Physics that vacuum is a pure insulator of heat. Thermos is made of two containers separated by a vacuum space which acts as an insulator of heat. Also the surface of thermos will be glassy which in turn helps in reduction of heat loss.
Why sides of thermos bottle are silvered?
Silver is a great heat and light reflector. That means if you store cold water in a thermos, the heat from outside cannot get into the thermos easily because the heat is reflected by the silver color of the thermos.
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.
Why is the inner of the thermos bottle is silvered?
because it radiates heat.
What 3 insulators that can be used in a thermos bottle?
Heat, cold, pollution

Why the outer body of inner bottle of thermos flask is made silver in colour?
because the take heat heat inside and not allowed it heat to get outside
Does putting hot water in a thermos bottle before you put hot coffee in it help to keep temperature?
Filling the bottle with hot water immediately before use pre-warms the bottle, because heat is transferred from the hot water to the bottle (and in the transfer, the hot water naturally cools a little). This readies the bottle for filling with hot coffee and because the bottle is already pre-warmed, it takes little or no heat from the coffee thus keeping the coffee closer to the temperature that it was when the flask was filled.
What is the job of a thermos?
To keep hot liquids hot and cold liquids cold by minimizing heat transfer between the inside of the thermos with the outside.
Thermos bottles are used to keep liquid what?
Thermos bottles are generally used to keep liquid from changing temperature for a longer period of time. Usually, one pours hot liquid into the bottle, and it will remain warm for longer, but they are also effective at keeping cold liquid cool.
What is a bottle to keep liquids hot?
a thermos or u can wrap heapes of foil around another bottel
