How does insulation affect heating and cooling?
Insulation prevents objects from conducting heat. It can also be applied around some object to prevent heat from escaping. A thermos is a good example of how insulation can prevent objects from rapid cooling.
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.
What is the use of double glass in thermos flask?
The vacuum space between the two silvered surfaces make efficient heat insulation against heat loss.
How the rate of heat transfer is reduced?
rate of heat transfer between two bodies can be reduced by providing insulation between the two. e.g. As in thermos flask. where the insulation prevents heat flow from liquid/tea stored inside the flask to outside atmosphere
Why does water inside a thermos flask gets cooled after few days?
This is due to insulation. Inside of the Thermos the liquid remains its placed temperature longer due to the insulating either stopping heat from reaching the fluid, or by stopping heat from leaving the fluid.
Why is there air space in a thermos bottle?
better insulation
Does the insulation in Thermos coolers degrade over time?
No... the insulation is created by a vacumm and a reflective mirror finish

What is a good insulator for heat?
Either a vacuum (thermos bottle) or air that can't move ... which is just what foam insulation is (tiny bubbles).
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.
Things used to keep heat in or cold out?
insulation blankets thermos flasks double glazing
What is the Application of a science project about heat retention?
There is the insulation of many things. This ranges from houses to thermos.
What is the Best Insulator for hot water?
The container that is easily accessible in everyday life that will help minimize the loss of heat effectively is Thermos. The Thermos is constructed in such a way that it kind of creates an isolated system. There is no perfectly isolated system in the universe.
Is a thermos good after 20 years?
Can be, if the vacuum is good. In glass thermos if the glass is not broken it is okay. In steel thermos if the vacuum has not been lost it will be. You can test a steel thermos by simply filling it with boiling water, if the outside of the thermos becomes hot the vacuum has been lost and one will need a new thermos.
What is the main reason stainless thermos bottles should not be washed in a dishwasher?
Stainless thermos bottles should not be washed in a dishwasher because the high heat and harsh detergents used in dishwashers can damage the vacuum insulation and outer coating of the bottle. This can lead to the loss of insulation properties and the formation of rust on the stainless steel surface.
What are some of the features of a thermos bottle that makes it a good container for keeping cold liquids cold and hot liquids hot?
The insulation of a thermos slows the transfer of heat into or out of it. So if there is a hot liquid inside, it cools down more slowly, and if there is a cold liquid inside, it warms up more slowly.
What would be a better calorimeter a thermos or a soda can?
A thermos would be better. They are built for insulation to keep temperature as constant as possible for as long as possible. A soda can is just a thin sheet of metal, and heat will be able to flow in and out of the can quite easily.
