A thermos reduces does not reduce heat transfer using convection, it reduces heat transfer BY convection. This is because there is a vacuum between the container of the liquid and the outer shell off the thermos. This means that no fluid will go round the inside conducting heat one way or the other.

What method of heat transfer are you using when you boil water?
convection
How does a thermos flask reduce heat loss by conduction?
Using vacuum as an insulator avoids heat loss by conduction. Heat transfer is minimised by reflective silver surfaces that are applied to the flask. This prevents thermal radiation from entering and escaping the flask.
What is a thermos flasks structure?
It is a container that keeps the tempreature constint by using certain matrials.
A circular flow of warmer fluid and cooler fluid?
We call the flow of thermal energy from warmer matter to cooler matter heat transfer, and we study this in thermodynamics. A link can be found below to check facts and learn more.
When does convection take place in everyday life?
Convection as a form of heat transfer occurs whenever something is hotter than the air around it. An example might be a stove-top that has been turned on or asphalt in the sun.

What is a good clinical example of using the principle of convection to transfer heat?
Heated, enclosed infant incubators.
Could you please use the science word thermos in a sentence?
They kept the liquid nitrogen in a thermos so it stayed cold. They used a thermos of oil to keep the sodium from contacting air and water.
How the thermos flask prevents heat loss by radiation?
A thermos bottle prevents heat transfer to the outside by using a vacuum between the walls of the bottle. The innerwall is usually made of glass while the outside wall is made of a plastic. Metal walls also exist. A vacuum doesnt conduct, since you need a substance to conduct heat. Same goes for convection, warm and cold liquids / gasses can rise and drop all they want, but the heat cant be passed on to the outside wall. Radiation is prevented by using reflective surfaces, which bounce back into the substance you are carrying in the bottle.
Where does convection happen?
Convection refers to the transfer of heat energy by the motion of a fluid such as air or water caused by differences in temperature within the fluid. Therefore convection happens wherever there is a fluid with a temperature gradient. This means that convection is happening continuously in the air around us and in bodies of water. A car heater and a convection oven are also considered to transfer heat by convection, but this is using the term liberally since the movement of the fluid (air) in these two cases is caused by a fan, not temperature gradient. So, while not perhaps being absolutely accurate examples of convection, still the heat is transferred through fluid motion.
How does heat transfer by radiation conduction and convection?
a thermos limits heat transfer through the walls of the thermos. that lets the fluid inside the thermos keeps its temperature nearly constant for a long period of time (whether the temperature is hot or cold).
What is a thermos flaske?
It is a container that keeps the tempreature constint by using certain matrials.
What are some everyday uses of conduction?
For convection cooking by using a convection oven.

Is glider use natural convection or create by itself convection by using any heating meterialial?
it uses natural convection
